Answer 1

Answer:

Now 

Amount is given To his Sons

= 1 % of his salary = x × 1/100 = x/100

again, Amount is Received by elder Son = 80% of x/100 = 80/100 × x/100

= 80x/10000 = 8x/1000 = x/125

it is given that he spends 80% of his share

So Amount saved by elder son = 20%

so, amount saved by elder son = 20% of amount gained by elder son

= 20 /100 × x/125

= x/625

a/c to question, amount saved by elder son =20 rs.

or, x/625 = 20

x = Rs 12,500
