Question

John earns 15000rs. every month. he spends 8900rs. what % of his salary does he save?

Answer 1

15000-8900 = 6100 ( money saved )

% of money spent = 6100/15000* 100
                              = 40.66%

Answer 2

Answer:  He saves $40\dfrac{2}{3} \%$ of his salary

Step-by-step explanation:

As given in question

Earnings of John =Rs. 15000

John spend = Rs. 8900

Therefore

John  saves =Earnings - Spending = Rs. 15000 - Rs. 8900=Rs. 6100

Now

Percent of savings of his salary= $\dfrac{\text {Savings}} {\text {Total salary} }\times 100$

$= \dfrac{6100}{15000} \times 100 = \dfrac{610}{15} = \dfrac{122}{3} =40\dfrac{2}{3} \%$

Hence, he saves $40\dfrac{2}{3} \%$ of his salary
