• ₹ 110

• ₹ 125

• ₹ 105

Answer 1

The difference between CI and SI in 2 years at 5% on ₹ 42000 is ₹ 105.

Explanation:

Step 1: Formula for the difference between CI and SI for 2 years

For 2 years, the formula is:

`CI - SI = (P xx r^2)/100^2`

Where:

• P = 42,000
• r = 5% per annum

This is a shortcut formula specifically for 2 years.

Step 2: Substitute the values

`CI - SI = (42,000 xx 5^2)/100^2`

`CI - SI = (42,000 xx 25)/(10,000)`

`CI - SI = (1,050,000)/(10,000)`

CI – SI = 105
