Question

Reema spend 1/2of her money in a shop.Then she spend 1/3of what is left on yhe bus fare.If she is finally left with rupees 20,how much did she have in the beginning?

Answer 1

Answer:

60 Rs

Step-by-step explanation:

Let X be the money Reema had in the beginning,

She spent 1/2 of money in shop, so that is 0.5X, so 0.5X is remaining

She spent 1/3 of remaining in bus fare. That is 1/3*0.5X,

The remaining money is Rs.20

The equation is,

0.5X-0.5x/3=20

Now multiply both sides by 3 to remove the denominator, we get

1.5X-0.5X=60

1X=60

X=60
