​

Answer 1

Step-by-step explanation:

SOLUTION :

The earning of Ravi per month = Rs 10000 (given)

He spend 15% of the money for his house rent

15% of Rs 10000

= 15/100x 10000

= Rs 1500

∴ Ravi spend Rs 1500 for his house rent.

He spend 12% of the money for food

12% of Rs 10000

= 12/100x10000

= Rs 1200

∴ Ravi spend Rs 1200 for food.

He spend 10% of the money for payment of bills

10% of Rs 10000

= 10/100x10000

= Rs 1000

∴ Ravi spend Rs 1000 for payment of bills.

Now,

Remaining money

= Total amount - used money

= 10000 - (1500+1200+1000)

= 10000 - 3700

= Rs 6300

Hence,

Ravi saves Rs 6300

Answer 2

Answer:- Here first we need to add the total % .

So, 15+12+10=37.

Therefore the total % are spends bye Ravi of his salary is 37%.

Now, for finding total amount of saving.

10000/100×37 = 3700

Therefore, total amount Ravi used is ₹3700 from ₹10000

Now, subtract total spending from total earning.

Therefore, 10000-3700 = 6300

Therefore, 6300₹ is saved by ravi every month.
