Answer 1

Answer:

Step-by-step explanation:

Mr. Manohar's income = A.

Amount given to elder son = 20% of A = 20/100 * A = A/5

Amount given to younger son = 30% of A = 3/10 * A

Balance = 100 % - 30% - 20% = 50% of A = 1/2 * A 

Donation given to school = 10% of A/2  =  10/100 * A/2 = A /20

Balance =  A/2 - A/20 

          = A * 9/20

So   9 A /20 = Rs 1,80,000

          A = Rs 1,80,000 * 20/9

              = Rs 4, 00, 000.

Income is Rs 4 hundred thousand.
