Ration is 4:8:5 .

Total amount in 1 Rupee coin is = Rs. 4x*1
Total amount in 2 Rupee coin is = Rs. 8x*2
Total amount in 5 Rupee coin is = Rs. 5x*5

So, 4x+16x+25x = 90; x=2
So no. of 5 rupee coin is = 5x = 10

assume that there are 4x,8x,5x coins of 1,2,5 rs respictively as for the question.
Then (4x*1)+(8x*2)+(5x*5)=90
then x=2
now there has 4,16,10 coins of 1,2,5 Rs respictively

Its simple!!
we will solve it by using the value of each coin.x be identity ratio
let the ratio be 4x,8x,5x
When we add this to become 90 as it says that the coins 1,2,5 are in ratio 4:8:5
we will multiply every ratio by their face value
4x*1+8x*2+5x*5=90
45x=90
x=2
Therefore the number of coins be Re 1=8,Rs2=32 Rs 5=10

4x*1+8x*2+5x*5=90(coz given ratio is 4:8:5)
45x=90
x=2
So no. of 5 rupee coin is = 5x = 10

S.SHAFI  (10 years ago)

ans) 10
---> 4x*1 + 8x*2 + 5x*5 = 90
---> 4x + 16x + 25x = 90
---> 45x = 90
---> x = 2
So, the ratio becomes 2*4:2*8:2*5 ==> 8:16:10
so, there are 8 Rs.1 coins, 16 Rs.2 coins and 10 Rs.5 coins...
