Question

Nirmala donates 10percent of her salary to charity and 20./. to temples and 30./. to her friend now still she had 6300ruppees find intial amount she had

Answer 1

Let the Nirmala's salary be Rs. x

Her expenditures:

Charity = 10 % of x
Temple = 20 % of x
Friends = 30 % of x

Her total expenditures = 60 % of x

Therefore her savings = 40 % of x

That is
6300 = (40/100) × x

x = 630 × 100 / 4

x = 630 × 25

x = Rs. 15750

I hope this answer helps you
