Answer 1

Question :-

Rahul got 20% more pocket money than his sister Amayra and Amayra got 20% more than her sister Pihu. If the total money received by all of them together is Rs. 5824, find how much pocket money did Pihu get.

Answer :-

• D option (Rs.1600)

Given :-

Rahul got 20% more pocket money than his sister Amayra and Amayra got 20% more than her sister Pihu. If the total money received by all of them together is Rs. 5824

To find :-

how much pocket money did Pihu get

Solution :-

let the pocket money Pihu got be x

then,the pocket money amayra got = 1.2x

and the pocket money Rahul got = 1.2 × 1.2 = 1.44x

now according to question we get,

$\sf⇢ \: x + 1.2 + 1.44x = 5824$

$\sf⇢1.2 + 1.2 + 1.44 = 3.64$

$\sf⇢3.64x = 5824$

$\sf⇢x = \cancel\frac{5824}{3.64} = rs.1600$

so therefore Pihu got rs.1600 as pocket money.
