B. Rs. 108000

C. Rs. 98000

D. Rs. 136000​

Answer 1

Answer:

B. Rs. 108000

Step-by-step explanation:

The total amount he spent = 10 + 14 + 12 + 15 + 10 = 61%

39% of Y = 518400

Y = (518400 x 100) / 39 = Rs. 1329230.77

Monthly salary = 1329230.77/12 = Rs. 110, 769.231 approximated to Rs.108000.

Answer 2

Total expenditure of Rahim is

$10 + 14 + 12 + 15 + 10 = 61\%$

Savings will be 39%

$39\% = 518400$

we have to calculate annual salary which is 100%

$100\% = \frac{518400 \times 100}{39}$

$= 1329230$

monthly salary will be

$\frac{1329230}{12} = 108000$

Hence the monthly salary will be Rs 10800
