Question
Jolly borrowed some money at compound interest for 4
years. What will be the amount required to return after 4 years? Statement I: If the amount was borrowed at simple interest, then after 10 years Rs 1200 was required to pay as simple interest. Statement II: The rate of interest is 12% per annum Statement III: The sum of money borrowed is 15 times the amount required to be paid as simple interest after 3 years. In each of the following questions, a question is followed by three statements numbered I, II and III. Read all the statements and answer accordingly which statement/s are sufficient to find the answer .Solution
From I: SI after 10 years is Rs 1200, so after 1 year = 1200/10 = Rs 120 so,SI of 1 year = Rs. 120 From III: Principal = 15 × S.I after 3 years or P = 15 × P× R ×3/100 or R = 100/45% So from I and II, SI =120 = P× R×1/100 = P × (100/45) /100 So we can find Principal. then we can find the required amount by CI formula So from I and II, SI =120 = P× R×1/100 = P × (12) /100 So we can find Principal, then we can find the required amount by CI formula
(22 × 52 ) + 4 × 6 = ? - √324
What should come in place of (?) question mark in the given expression.
 (25% of 320) + (3/8 of 400) − 30 = ?
(5832)1/3  × 10.11 × 11.97 ÷ 16.32 = ? + 45.022
82% of 400 + √(?) = 130% of 600 - 85% of 400
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
Simplify: (1 ÷ 0.08)
What should come in place of (?) question mark in the given expression.
{ (144 ÷ 12) × 5 } − (18 ÷ 3) = ?
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 ÷ 7)
464 + 181 +? = (154 × 25) - (15) 2 Â
15% of 1800 + 22 = ?Â
