Question

Bansi has 3 times as many two rupees coins as he has five rupees coins. if he has in all a sum of is 77, how many coins does he have?
​

Answer 1

Let the number of five-rupee coins that Bansi has be 'x'.

Then the number of two-rupee coins he has is 3 times x or 3x.

The amount Bansi has:

• From 5 Rupee coins = ₹5 × x = ₹5x
• From 2 Rupee coins = ₹ 2 × 3x = ₹6x

Hence the total money he has = ₹11x

But this is given to be ₹77 ; Therefore,

$11x = 77$

$= > x = \frac{77}{11} = 7$

Thus,

• Number of five-rupee coins = x = 7
• Number of two-rupee coins = 3x = 21

(You can check that the total money with Bansi is ₹ 77).
