GATE | Sudo GATE 2020 Mock I (27 December 2019) | Question 8
A box contains Rs 350 in the form of coins of one rupees, 50 paise and 25 paise. The number of 25 paise coins is double the number of one rupee coins and four times the number of 50 paise coins. How many 25 paise coins are there in the box?
Explanation: Given ratio of coins,
25 paise 50 paise 100 paise 4x : 1x : 2x
4x *25 + 1x * 50 + 2x * 100 = 35000 100x + 50x + 200x = 35000 350x = 35000 x = 100
So, number of 25 paise coins = 4x = 4*100 = 400.
