investment of Rs. ‘x’. Neha's share in the initial investment was 45%, and Tara invested the rest. In the second year, Neha raised her investment by 15%, and Tara raised hers by 25%. The combined second-year investment stood at Rs. 14,100. What was the initial total investment ‘x’?Solution
ATQ,
Neha’s investment = 45% of x = Rs. 0.45x Tara’s investment = 55% of x = Rs. 0.55x After one year, Neha’s amount = 115% of 0.45x = Rs. 0.5175x Tara’s amount = 125% of 0.55x = Rs. 0.6875x According to the question, 0.5175x + 0.6875x = 14,100 1.205x = 14,100 ⇒ x = 14,100 / 1.205 = Rs. 11,700
