Question

Mr.Mehra had Rs. 1,20,000. He gave one third of of his money to his daughter,
one fifth to his son and remaining to his wife. How much money Mr. Mehra gave
to his wife?

Answer 1

Answer:

56,000

Step-by-step explanation:

The money given to his daughter is one-third of his money. That is,

$\frac{1}{3}$x 120000 = 40,000

The money given to his son is one-fifth of his money. That is,

$\frac{1}{5}$x 120000 = 24,000

The remaining money can be obtained by adding 40,000 and 24,000 and subtracting it with his whole money. That is,

1,20,000 - (40,000+24,000)

=1,20,000 - 64,000

56,000.

Therefore the money given to his wife will be 56,000

Answer 2

Answer:

Step-by-step explanation:

Let Mr. Mehra has money = 1

Money given to his son = 1/3

And money given to his daughter = 1/5

∴ Remaining money given to his wife

= 1 – (1/3 + 1/5)

= 1 – (5 + 3)/15

= 1 – 8/15 = (15 – 8)/15 = 7/15

∴ 7/15 of his money = Rs. 91000

∴ Total money = Rs. (91000 × 15)/7

= Rs. 13,000 × 15 = Rs. 1,95, 000
