Q:

Manisha went to shop with certain amount, with which she can buy 50 Chacobar or 40 Fivestar. She uses 10% amount for petrol and out of the remaining balance, she purchases 20 Fivestar and some Chacobar. Find the number of Chacobar she can buy?

A) 20	B) 24
C) 26	D) 28

Answer & Explanation Answer: A) 20

Explanation:

Let the total amount be 200 {L.C.M of 40 and 50}

Chacobar C.P. = 200/50 = 4

Fivestar C.P = 200/40 = 5

Remaining Money after petrol = [200 - 200×10%] = 180

Remaining money after buying fivestars = [180 - 20×5] = 80

So number of Chacobar she can buy = 80/4 = 20

A) 12.5%	B) 18.75%
C) 16.55%	D) 17.80%

Answer & Explanation Answer: B) 18.75%

=> What % of 80 is 15

Let it be 'p'

=> $\frac{p x 80}{100} = 15 \Rightarrow p = \frac{15 x 100}{80} \Rightarrow p = \frac{1500}{80} = 18.75$

Therefore, 15 is 18.75% of 80 => 18.75% of 80 = 15

Example::

Now, in the similar way we can find 15% of 80 =?
