Question

Alka spend 90% of the money that she receives every month, and saves ₹120. How much money does she get monthly?

Answer 1

She have 1080 Rs money

Answer 2

let the total money be x

now money she spends = 90x/100

money she saves = 120

NOW

90x/100 + 120 = x

x - 90x/100 = 120

10x/100 = 120

x = 120 x 100/10

x = 1200

she earns 1200
