1. A, B, C are partners in a business. A, whose money has been used for 4 month’s, claims 1/8 of the profit. B, whose money has been used for 6 month’s claims 1/3 of the profit. C had invested tk 1560 for 8 months. How much money did A and B contribute?

Solution :

Let total profit x tk. 
Then, A’s share =x/8;B’s share =x/3
C’s share =x-(x/8+x/3)=13x/24
Ratio =x/8:x/3:13x/24=3:8:13
Again let A invested p for 4 month’s and B invested q for 6 months. So their investment ratio 4p :6q :1560*8=3:8:13
Therefore p=720 & q=1280.

Ans: 720 and 1280

5. In a certain class, 1/5 of the boys are shorter than the shortest girl in the class, and 1/3 of the girls are taller than the tallest boy in the class. If there are 16 stu­dents in the class and no two people have the same height, what percent of the students are taller than the shortest girl and shorter than the tallest boy?

Solution:

Since total boys and girls = 16
Boys must multiple of 5 and girls must multiple of 3 so
Total boys = 10
Shorter boys = 10*1/5 = 2
Total girls = 6
Taller girls = 6*1/3 = 2
ATQ,
Shortest girl = 1 and Tallest boy = 1
Shorter boys = 2 and Taller girls = 2
So
Taller than shortest girls and shorter than tallest boy =(16-2-2-1-1)=10
10*100/16 = 62.5%

Ans: 62.5%
