Question
At what rate of interest per annum, compounded annually,
will an amount of ₹8,000 yield a compound interest of ₹904.2 in 2 years?Solution
A=P+CI = 8000+904.2=8904.2 ATQ- 8904.2 = 8000 (1 + r/ 100)2 8904.2/ 8000 = (1+ r/ 100)2 44521/40000 = (1+r/100)2 211/200 = 1 +r/100 r/100 =11/200 r =11/2=5.5% r=5.5% A=P+CI = 8000+904.2=8904.2 ATQ- 8904.2 = 8000 (1 + r/ 100)2 8904.2/ 8000 = (1+ r/ 100)2 44521/40000 = (1+r/100)2 211/200 = 1 +r/100 r/100 =11/200 r =11/2=5.5% r=5.5%
(500 × 6 ÷ 10) - (√256 + 8) = ?
22% of 400 + √ ? = 34% of 800 - 25% of 400
(2/5)(32% of 4500 – 440) = ? × 8
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
What will come in the place of question mark (?) in the given expression?
96 ÷ (9 - 6.6) + 17.5 X 6 = ? ÷ 8
13 X ? = 85 X 4 + √81 + 2
45% of 360 - 160 + ? = √324
((67)32 × (67)-18 / ? = (67)⁸
4567.89 - 567.89 - 678.89 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
