Given:
In 2023, a part of Rs. 45,000 is invested in company X
The rest was invested in company Y for 1 year
The total interest received is Rs. 3100
Concept Used:
Simple interest (SI) = (P × R × T)/100
Where, P = principal amount, R = rate of interest, and T = time of investment
Calculation:
Let, Rs. a is invested in X and Rs. (45000 - a) is invested in Y
According to the question,
(6a/100) + (45000 - a) × 8/100 = 3100
⇒ 6a + 360000 - 8a = 310000
⇒ 2a = 50000
⇒ a = 25000
∴ The amount invested in X was Rs. 25000
