Question

How many 50 paise coins make 10 Rupees?
A.10coins
B.20 coins
C.30 coins
D.40 coins

Answer 1

Hint: In this problem, we have to find the number of 50 paise coins, which will be equal to Rs.10. We know that 1 Rupees is equal to 100 paise, so we can now say that two 50 paise coins make 1 rupee. If we multiply 2 and 50, we will get 100 paise, which is equal to 1 rupee, similarly, we can find what number can be multiplied to 50 paise, to get 1000 paise, which will be equal to 10 rupees.

Complete step-by-step solution:
Here we have to find the number of 50 paise coins, which will be equal to Rs.10.
We know that 1 Rupees is equal to 100 paise.
Where, we will have two 50 paise in one rupee,
We can now write it as,
\[\Rightarrow 50\times 2=100p=Rs.1\]
Now we can find the number multiplied to 50, which gives 1000 paise (Rs.10)
\[\Rightarrow 50\times x=1000\]
We can now divide 50 n both sides, we get
\[\Rightarrow x=\dfrac{1000}{50}=20\]
There are 20 coins of 50 paise and 10 rupees.
Therefore, the answer is option B. 20 coins.

Note: We should always remember the conversion methods, to convert the rupees to paisa and paise to rupees. We should remember that 1 rupee is equal to 100 paise, where two 50 paise coins give rupee 1. If one rupee is 100 paise, then 10 rupees will have 1000 paise, which is the multiplication of 10 and 100.
