Answer:

John is 31

Ella is 25

Step-by-step explanation:

Let sister's age be x, then John's age is (x + 6). So from sentence 2,

(3x) - 2(x + 6) = 13

3x - 2x - 12 = 13

x = 13 + 12 = 25

and x + 6 = 31

Manish and Jhanavi each receive an equal bonus. Manish has 1/2 fraction of allowance as saving accounts , 1/4 of the fraction he
Valentin [98]

Answer:

Manish has Rs630 while Jhanavi has Rs168.

Step-by-step explanation:

The fraction Manish would have left would be subtracting the fraction on savings as well as that spent on the mall. Which would be;

1 -( 1/2 + 1/4)=1 -3/4 = 1/4

Meaning Manish had 1/4 of his allowance left on him.

Which means 1/4 × Rs. 2520=Rs630

Similarly for Jhanavi, we have :

The fraction left as

1-(1/3 +3/5) = 1 - ( 14/15) = 1/15

Meaning 1/15 of the allowance got remains which is;

1/15 × Rs. 2520= Rs.168
