Ram has 18 coins in the denominations of rs1,rs2, rs5. If their total value isrs54 and the number ofrs2 coins are greater than that ofrs5coins then find the number ofrs1 coins with him

Answer»

Answer:

Let RS. 1 be x, rs.2 be y, rs. 5 be z.

ATQ,

(x+y+z= 18) first equation

(x+y+2+z x 5= 54). second equation

(y+4z=36)

given, (y > z)

z=7 and y= 8

x= 18-8-7= 18-15= 3

so, x=3

Hence, rs.1 coins are 3, rs.2 coins are 8 and rs.5 coins are 7.
