S.I = PRT/100

= 75×40/12
=25×10=250
= 750×10×40/100×12

Heya!
Since the rate is given per annum, let's find the interest for 3 years first.
SI = PRT/100
where,
P = 750
R = 10 % pa
T = 3 years
SI = 750 × 10 × 3 / 100 = ₹225
SI for 1 year = 225/3 = 75
SI for 1 month = 75/12 = 6.25
SI for 4 months = 6.25 × 4 = ₹25
Total SI for 3 years and 4 months
= 225 + 25 = ₹250
Total Amount
= 750 + 250 = ₹1000
Hope it helps!!
