Question

A lady has 50 paise coins and 1 rs coins in his purse. If he has 40 coins in all totalling Rs 30, find the number of coins of each type she has

Answer 1

Answer:

20 coins of 50 paise value and 20 coins of 1 rs value.

Step-by-step explanation:

Let number of 50 paise coin be X and no. of 1 rs coin be Y

Total number of Coin is 40

∴ X+Y=40.---------(eqn. 1)

Now total value of coins is Rs. 30.

∴ 1/2 X + Y= 30-------(eqn. 2)

Subtracting eqn. 2 from eqn 1 we get

⇒X=20

Putting value of X in eqn. 1 we get value of Y as 20.

Thus the lady would have 20 coins each of 50 paise and Rs.1
