Answer:
Step-by-step explanation:50 PAISE = RS. 0.50 NO. OF RS. 0.50 COIN = 4x COST OF RS. 0.50 COIN = 4X×RS. 0.50
= RS. 2x NO. OF RS. 2 COIN = 3x
COST OF RS. 2 COIN = RS. 2x3x
= RS. 6x
NO. OF RS. 5 COIN = 2x COST OF RS. 5 COIN = RS. 5x2x
= RS. 10x
A/Q,
2x+6x+10x=396
=> 18x=396
=> x-396/18
=>.
x=22
therefore, no. of RS. 5 coin = 2x = 2 x 22 = 44
no. of RS. 2 coin = 3x = 3x22 = 66 no. of RS. 0.50 coin = 4x = 4 x 22 = 88
