Answer:

The total amount is Rs. 9240

The interest is Rs. 1740

Step-by-step explanation:

Given the Principal = 7500

We know that A = P [ (1+\frac{R_1}{100} ) (1+\frac{R_2}{100} ) ]

where A is the amount

R₁ = Rate of interest for first year

R₂ = Rate of interest for second year

Therefore, on substitution, we get

A = P [ (1+\frac{R_1}{100} ) (1+\frac{R_2}{100} ) ]

    = 7500 [ (1+\frac{10}{100} )\\ (1+\frac{12}{100} ) ]

    = 7500 [ (\frac{110}{100} ) (\frac{112}{100} ) ]

    = 7500 [ (\frac{110}{100} ) (\frac{112}{100} ) ]

    = 9240

Therefore, the total amount is Rs. 9240

We know that Amount = Interest + Principal

=> 9240 = Interest + 7500

=> interest = 1740

Therefore, the interest is Rs. 1740
