Basics of AverageEasy
Three friends went for a picnic. First brought five apples and the second brought three. The third friend however brought only Rs. 8. What is the share of the first friend?
Answer & solution
Correct answer: 7
- A
8
7
- C
1
- D
None of these
Solution
There are 8 apples available for 3 friends. So, share of apples of each person = 8/3
The 1st person gives out 5 − 8/3 apples = 7/3 apples to 3rd person
The 2nd person gives out 3 − 8/3 apples = 1/3 apples to 3rd person
∴ 3rd person will distribute Rs. 8 in the ratio 7 : 1 to 1st and 2nd person respectively and thus Rs. 7 and Rs. 1 are given to them respectively.
∴ Share of 1st friend is Rs. 7.
Hence, option (b).
