Question
Palash invest thrice the sum invested by Vicky and
withdraws half of the sum after 3 months and again withdraws half of the remaining sum after 5 months. Find ratio of profit share of Palash to Vicky  at the end of a year?Solution
Let investment of Vicky is Rs.8x. So, investment of Palash = Rs.24x Required ratio = (24x x 3 + 12x x 5 + 6x x 4) : 8x x 12 => (72x + 60x + 24x) : 96x => 156x : 96x => 13:8

(804/65) ÷ (11/798) × (129/131) = ?
? * 5.92 = (450.08 ÷ 9.99) % of 5180 - 921.12
15.232 + 39.98% of 539.99 = ? × 6.99
