Ganeshi Lal distributed ₹25300 among his three sons A, B, C in such a way that the amount of their parts at 10% simple interest in 2 years, 3 years and 4 years will be equal. A's share is?
Answer & explanation
Correct answer: option 1
Let the three parts = P1, P2, P3
⇒ Total interest on P1 = 10 × 2 = 20%
⇒ Total interest on P2 = 10 × 3 = 30%
⇒ Total interest on P3 = 10 × 4 = 40%
ATQ,
P1 × 120% = P2 × 130% = P3 × 140%
P1 × 12 = P2 × 13 = P3 × 14
P1 : P2 : P3 = 91 : 84 : 78 = 253R
⇒ 253R = 25300
⇒ R = 100
A's share = 9100
