Question

A man spent 3/7 on food and 7/10 of remaining on house rent .what fraction of income is left with him if money left with him is 2400 what is his monthly income

Answer 1

Answer:

Step-by-step explanation:

3/7=food

so remaining=7/7-3/7=4/7

therefore,

house rent= 7/10 of 4/7

                 = 7/10 x 4/7

                 = 4/10

food=3/7=15/35

house rent= 4/10=14/35

15/35+14/35=29/35

fraction of income left=35/35-29/35 =6/35

6/35= 2400

so 1/35 = 400

therefore, the monthly salary is 35/35=400 x35

                                                              = 14000
