Answer: Option A. -> 625
Answer: (a).625

Answer: Option A. -> Rs.432
Answer: (a)Using Rule 1,C.I. = P$[(1 + R/100)^T - 1]$246 = P$[(1 + 5/100)^2 - 1]$246 = P$[(21/20)^2 - 1]$246 = P$({441 - 400}/400)$246 = ${41P}/400$P = ${246 × 400}/41$ = Rs.2400SI = $\text"Principal × Time × Rate"/100$= ${2400 × 3 × 6}/100$ = Rs.432

Answer: Option A. -> Rs.400
Answer: (a)If the principal be P thenC.I. = P$[(1 + R/100)^T - 1]$420 = P$[(1 + 10/100)^2 - 1]$420 = P$({121 - 100}/100)$420 = ${P × 21}/100$P = ${420 × 100}/21$ = Rs.2000S.I. = ${PRT}/100 = {2000 × 10 × 2}/100$ = Rs.400Using Rule 10,Here, C.I. = Rs.420, R = 10%, S.I. = ?C.I. = S.I.$(1 + R/200)$420 = S.I.$(1 + 10/200)$420 = S.I.$(210/200)$S.I. = ${420 × 200}/210$ = Rs.400
