Answer: Option C. -> E86

The sequence is 86V, 2KN, ?19, __.The logic is as follows
8⁺³ 6⁺³ V⁺³, 2⁺³ K⁺³ N⁺³ , ?⁺³ 1⁺³ 9⁺³, E⁺³ 8⁺³ 6,Hence, E86 is the next term.

Question 52. In a certain code language, '+' means '/', '/' means '*', '*' means '-', '-' means '+'.(10 - 5) / 50 * (25 * 5) / 40

Answer: Option A. -> -50

The given expression(10 - 5) / 50 * (25 * 5) / 40becomes(10 + 5 ) * 50 - (25 - 5) * 40Using BODMAS rule,(10 + 5 ) * 50 - (25 - 5) * 40= 15 * 50 - 20 * 40= 750 - 800= -50

Discuss Question

Answer: Option B. -> 8

'+' means '*', '*' means '-', '-' means '/' and '/' means '+'.The given expression is9 + 4 - 6 * 6 / 8On converting this expression as per the directions, we get the expression9 * 4 / 6 - 6 + 8We simplify this expression using BODMAS rule,9 * 4 / 6 - 6 + 8 = 36 / 6 - 6 + 8 = 8.

Question 54. In a certain code language, '+' means '/', '/' means '*', '*' means '-', '-' means '+'.5 * 10 - 15 / 20 + 25 / 30

Discuss Question

Answer: Option C. -> 355

'+' means '/', '/' means '*', '*' means '-', '-' means '+'.The given expression is5 * 10 - 15 / 20 + 25 / 30According to the given direction, the above expression becomes5 - 10 + 15 * 20 / 25 * 30Using BODMAS rule,5 - 10 + 15 * 20 / 25 * 30= -5 + 300 / 25 * 30= -5 + 12 * 30= 355.

Question 55. In a certain code language, '+' means '*', '*' means '-', '-' means '/' and '/' means '+'.10 + 10 * 10 - 10 / 10

Discuss Question

Answer: Option A. -> 109

The given expression is10 + 10 * 10 - 10 / 10As per the directions, it becomes
10 * 10 - 10 / 10 + 10Using BODMAS rule,10 * 10 - 10 / 10 + 10= 100 - 1 + 10= 109.

Question 56. In a certain code language, '+' means '*', '*' means '-', '-' means '/' and '/' means '+'.16 * 4 / 4 + 14 - 2

Discuss Question

Answer: Option C. -> 40

The given expression16 * 4 / 4 + 14 - 2becomes16 - 4 + 4 * 14 / 2as per the given directions.Using BODMAS rule,16 - 4 + 4 * 14 / 2= 12 + 56 / 2= 12 + 28= 40

Question 57. a + b means a is neither less than nor equal to b.a - b means a is neither smaller nor greater than b.a = b means a is not less than b.a * b means a is not greater than b.a / b means a is neither greater than nor equal to b.Statement: A + B, B * C, C * DConclusions: I. A + D II. A = C

if only conclusion (I) follows
if only conclusion (II) follows
if both conclusions (I) and (II) follows
if neither (I) nor (II) follows
if either conclusion (I) or (II) follows

Discuss Question

Answer: Option D. -> if neither (I) nor (II) follows

a + b means a > b, a - b means a = b, a = b means a > b, a * b means a A > BB * C => B C B D which can not be definitely determined because A could be either greater than, less than or equal to D.Conclusion (II): A = C => A > CWhich can not be determined as A can be less than C.

Question 58. P @ Q means P is neither greater than nor equal to Q.P # Q means P is not less than Q.P $ Q means P is neither greater than nor less than Q.P © Q means P is not greater than Q.P % Q means P is neither lesser than nor equal to Q.Statements: A % B, B # C, C @ D, D % EConclusions: I. A % C II. D @ A III. B # E

Only I follows
Only II follows
Only III follows
Either I or II follows
None follows

Discuss Question

Answer: Option A. -> Only I follows

P @ Q => P < QP # Q => P â‰¥ QP $ Q => P = QP © Q => P â‰¤ QP % Q => P > QThe Statement isA % B => A > BB # C => B â‰¥ CC @ D => C < DD % E => D > EBy Combining the aboveStatements we getA > B â‰¥ C < D > E.Conclusion I: A % C => A > C follows.Conclusion II: D @ A => D < A, doesnot follow.Conclusion III: B # E => B â‰¥ E, doesnot follow.
Only I follow.

Question 59. p Ûž q means p is neither less than nor equal to q.p @ q means p is neither greater than nor equal to q.p # q means p is not less than q.p âˆ† q means p is not greater than q.p â–¡ q means p is neither smaller nor greater than q.Statement: k â–¡ l, l âˆ† m, m @ nConclusions: I. l @ n II. m # k

if only conclusion (I) follows
if only conclusion (II) follows
if both conclusions (I) and (II) follows
if neither (I) nor (II) follows
if either conclusion (I) or (II) follows

Discuss Question

Answer: Option C. -> if both conclusions (I) and (II) follows

p Ûž q means p > qp @ q means p < qp # q means p â‰¥ qp âˆ† q means p â‰¤ qp â–¡ q means p = qThe statement is (i) k â–¡ l (ii) l âˆ† m (iii) m @ ni.e, k = l, l â‰¤ m, m < n=> k = l â‰¤ m < nConclusion I: l @ n => l < n is trueHence I follows.Conclusion II: m # k => m â‰¥ k is true.Hence II follows.

Question 60. a + b means a is neither less than nor equal to b.a - b means a is neither smaller nor greater than b.a = b means a is not less than b.a * b means a is not greater than b.a / b means a is neither greater than nor equal to b.Statements: P + Q, Q - R, R + SConclusions: I. P = S II. P / R

if only conclusion (I) follows
if only conclusion (II) follows
if both conclusions (I) and (II) follows
if neither (I) nor (II) follows
if either conclusion (I) or (II) follows

Discuss Question

Answer: Option B. -> if only conclusion (II) follows

a + b means a > b, a - b means a = b, a = b means a â‰¥ b, a * b means a â‰¤ b and a / b means a < b.According to the Statement:P / Q => P < QQ - R => Q = RR + S => R > SP < Q = R > SConclusion (i): P = S => P â‰¥ S, cannot be definitely determined because P can be less than S.Conclusion (ii): p / R => P < RAs P < Q and Q = RP < R follows.
