Question

Ravi spends 2/5 of his income on food and another 7/15 of his income on entertainment.He saves the rest of his income. If his income is rupees 21000 ,find the fraction of his income saves.

Answer 1

Answer:

2/15

Step-by-step explanation:

The part about 21000 is unnecessary data.

We know that total ratio always 1.

7/15 is spent on entertainment.

2/5 on food

= 2*3/5*3 on food

=6/15 on food.

thus he spends a total of 7/15 + 6/15 = 13/15

1 - 13/15 = 2/15 is what he is left with.

Answer 2

21000 = 2\5 + 7/15 + x

21000 = 13/15x

x = 13/15 divide by 21000

x = 315000/13

21000 = 315000/13
