Question

Dev has 3 times as many four-rupee coins as he has ten -rupee coins. If he has in all a sum of Rs 154 , How many coins of each denomination does he have ? please help step by step answers​

Answer 1

Answer:

Step-by-step explanation:

Let 10 rupee coins be x

So, 4 rupees coins will be 3x

Value of 4 rupee coins = 4(3x)

= 12x

Value of 10 rupee coins = 10(x)

= 10x

ATQ,

12x+10x=154

22x=154

X=154/22

X=7

3x=7*3

21

Therefore, he has seven ₹10 coins and twenty one ₹4 coins
