Question
'P' invested a certain amount at
21% per annum simple interest for 2 years. If he had instead invested the same amount at 20% per annum compound interest, compounded annually for 2 years, the interest earned would have been Rs. 150 more. What was the sum invested by 'P'?Solution
ATQ, Let the sum invested by 'P' be Rs. 'p'. ATQ; {(p × 21 × 2)/100} + 150 = p × (1.2)2 - p (42p + 15000) = 0.44p X 100 Or, 2p = 15000 So, p = 7,500 So, sum invested by 'P' = Rs.7,500
What will come in the place of question mark (?) in the given expression?Â
? X (62 - 20) + 60 X 5 = √1296 X 25 - 35 X 43...
(12% of 1250 + 85% of 400) x 10 = ?2
√ [? x 11 + (√ 1296)] = 16
√441 * 7 – 10% of 250 + ? = 140% of 120
(7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
