Question
A gave 30% of amount to B. B gave 20% of amount received
from A to C. If amount received by C from B is Rs.192, then find the amount received by B from A.Solution
Let A had Rs.x with him. According to question, => 30% of 20% of x = 192 => 0.06x = 192 => x = 3200 Amount received by B from A = 30% of 3200 = Rs.960
