Answer:
he will buy two plates , three glasses and eighty one spoons
Given:
(i) One person has Rs 100 with him.
(ii) Plates cost Rs 5 each
(iii) Glass costs Rs 3 each
(iv) 40 spoons cost Rs 1.
To find:
(i) Number of items he can buy by spending Rs 100 fully.
Solution:
First of all let us buy 40 spoons for Rs 1.
Money remaining = Rs (100-1) = Rs 99
As 99 is not perfectly divided by 5, the entire money will not get exhausted by buying the plates only.
So, number of plates = Total money/Price of 1 plate
= 99/5
= 19.8
≈ 19 plates [Number of items cant be fractional]
19 plates costs Rs (19*5) = Rs 95
Money left = Rs (100-95-1)
= Rs 4
From Rs 4, we can get 1 glass, which costs Rs 3.
Now, money remaining = Rs (4-3)
= Rs 1
From Rs 1, we can buy another 40 spoons.
Thus entire Rs 100 is exhausted and we have bought:
1) 19 plates
2) 1 glass
3) 80 spoons.
