Question
Palash invest twice the sum invested by Vicky and
withdraws half of the sum after 4 months and again withdraws half of the remaining sum after 2 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.16x Required ratio = (16x ×  4 + 8x ×  2 + 4x ×  6) : 8x ×  12 => (64x + 16x + 24x) : 96x => 104x : 96x => 13:12
