Question
Sneha deposited Rs. ‘R’ in a bank offering compound
interest of 13% p.a. compounded annually. After 3 years, she invested the amount received from the bank in scheme ‘M’ and ‘N’ in the ratio of 4:3 respectively. Scheme ‘N’ offers compound interest of 17% p.a. compounded annually while scheme ‘M’ offers simple interest of 16% p.a. If total interest received by her from schemes M and N together at the end of 2 years is Rs. 3564, then find the value of ‘R’.Solution
ATQ Let amount invested in scheme ‘M’ and scheme ‘N’ be Rs. ‘4v’ and Rs. ‘3v’, respectively. So, 0.16 × 2 × 4v + 0.36 × 3v = 3564 Or, 1.28v + 1.08v = 3564 Or, 2.36v = 3564 Or, v = 1510.17 So, R = (4 × 1510.17 + 3 × 1510.17)/(1.13 × 1.13 × 1.13) = Rs. 8000
What is the value of (152+82) ÷17
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?560 ÷ 14 × 3 – 25 = ?
What will come in the place of question mark (?) in the given expression?
35 X 72 + 35 X 28 = ? X √16
What will come in the place of question mark (?) in the given expression?
{(5400 ÷ 30 of 12) × 20 + 200} = ? % of 1000
8 × 12 + 110 ÷ 5 = 72 + ?
25% of 1000 + 10% of 150 – 22 × ? = 45
Determine the simplified value of the given mathematical expression.
324² × 36 ÷ 18⁵ × 1120 =?
120% of 25 + 80 X 2 = ?2 - 6
