Question

If the ratio of 2 and 5 coins is 4:5 and there are total amount is 66 in the box, then how many2 coins are there in
the box?​

Answer 1

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
