ATQ, The amount invested in SIP 'A' and SIP 'B' is Rs. ‘a’ and Rs. ‘b’ respectively. ATQ, a – b = 400 --------(i) Also, a × 5% × 4 – b × 8% × 3 = 48 0.2a – 0.24b = 48 ----------(ii) Solving both equations, we get, a = 1200 and b = 800 Therefore, total amount invested in both SIP's together = 1200 + 800 = Rs. 2000
