Answer» 15000 rupees.Step-by-step explanation:Let X be the AMOUNT deposited at the RATE of 15% pa, Since, the total deposited amount = 25000 rupees, ⇒ The amount deposited at the rate of 18 % pa = (25000 - x) rupees, Thus, the total interest in one year = 15 % of x + 18 % of (25000 - x) = 0.15 x + 0.18(25000-x) According to the question, 0.15 x + 0.18(25000-x) = 4050 ⇒ 0.15x + 4500 - 0.18x = 4050 ⇒ -0.03x= 4050 - 4500 ⇒ -0.03x = -450 ⇒ x = 15000 Hence, the amount deposited in 15 % pa = 15000 rupees.
