Explanation:
Rachit borrowed 15,000 from his

15% per annum and the remaining
amount at the rate of 18% per annum

- Interest for Rs.3000 = 15%
- Interest for remaining rupees = 18%
- Time = 4 years

To Find:-
- Total Interest in 4 years
════◄••❀••►════
Formula Used:-
- S.ɪ. = ( P × R × T ) ÷ 100
════◄••❀••►════
Solution:-
➥ Money which have Interest of 18%
= Total money- 3000
= 15000 - 3000
= Rs. 12000
➥ Interest earned in 4 years on the sum of Rs.3000
= ( P × R × T ) ÷ 100
Here, Principal = Rs.3000 , Rate = 15% , Time = 4years.
So, Interest
= ( 3000 × 15 × 4 ) ÷ 100
= ( 3000 × 60 ) ÷ 100
= 180000 ÷ 100
= Rs. 1800
➥ Interest earned in 4 years on the sum of Rs.12000
= ( P × R × T ) ÷ 100
Here, Principal = Rs.12000 , Rate = 18% , Time = 4years.
So, Interest
= ( 12000 × 18 × 4 ) ÷ 100
= ( 12000 × 72 ) ÷ 100
= 864000 ÷ 100
= Rs. 8640
➥ Total Interest
= Interest on Rs.3000 + Interest on Rs.12000
= 1800 + 8640
= Rs. 10440
