Solution
Surf gave 25% of her monthly salary to her mother.Remaining is 75%
15% of 75% was given for rent and 25% of 75% was kept for monthly expenses.
Remaining 60% of 75% was put in Bank account.
% of his monthly salary and 40% of remaining 65% of his monthly salary = 43290
Let his monthly salary be Rs.X
25% of X + 60% of 75% of X =42,000
0.25 X + 0.45 X =42,000
0.70 X = 42,000
X = 42,000 / 0.7 =60,000
