Of the three numbers, second is twice the first and also thrice the third. If the average of the three numbers is 44, the largest number is :
Options:
A . 36
B . 108
C . 24
D . 72
Answer: Option D Answer: (d)Let third number be x. ∴ Second number = 3x and first number = ${3x}/2$ Now, x +3x+${3x}/2$=3×44⇒ ${8x+3x}/2$=3×44⇒ 11x = 6 × 44 ⇒ x=${6×44}/11 = 24$ ∴ The largest number = 3x = 3 × 24 = 72
