P₁ = 12500
r₁ = 15%
t₁ = 3 years
interest, I₁=P₁*r₁*t₁/100 = 12500*15*3/100 = 5625

P₂ = 15000-12500=2500
r₂ = 18%
t₂ = 3 years
interest, I₂=P₂*r₂*t₂/100 = 2500*18*3/100 = 1350

Total interest, I=I₁+I₂=5625+1350 = 6975

Case i) P = Rs 12500 and R = 15%, T = 3 yrs

I =  \frac{PTR}{100}

 \frac{12500*3*15}{100}

= Rs 5625

case ii) P = Rs 2500   R = 18% and T = 3 yrs

I =  \frac{PTR}{100}

 \frac{2500*3*18}{100}

= Rs 1350

Total Interested he earned = Rs 5625 + Rs 1350 = Rs 6975
