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 |
