Answer 2

Answer:

The amount of money left with Amit is Rs. 12800.

Step-by-step explanation:

To find: The money left with Amit.

Monthly income of Amit = Rs 32000.

Fraction of income he spends on food = 1/4

∴ Amount of money he spends on food = 1/4  ×Rs 32000  =Rs 8000.

Remaining income= Rs 32000 – Rs 8000 = Rs 24000.

From this remaining income,  

Fraction of income he spends on house rent = 3/10

∴ Amount of money he spends on house rent = 3/10  ×Rs 24000 =Rs 7200.

Remaining income= Rs 24000 – Rs 7200 = Rs 16800.

From this remaining income,  

Fraction of income he spends on education of children = 5/21

∴ Amount of money he spends on education of children = 5/21  ×Rs 16800  =Rs 4000.

∴ Amount of money still left with him = Rs 16800 – Rs 4000 = Rs 12800
