Question
Rs. (x + 800) is invested at 12%
simple interest per annum for 5 years. The interest earned is Rs. (x - 320). If Rs. (x - 400) is invested at 8% simple interest per annum for 4 years, how much less will the interest earned be compared to the previous interest earned?Solution
ATQ,
Case I : Principal: x + 800 = 2000+800 = 2800 Interest: x β 320 = 2000 β 320 = 1680 Case II: Principal: x β 400 = 2000 β 400 = 1600 Interest: (1600Γ8Γ4)/100 = 512 Difference:1680 β 512 = 1168 Therefore, the second interest is Rs. 1168 less than the first.
8 Γ 9 + ? β 6 Γ 11 = 12 Γ 8
32.5% of 40 + (13)2 + 102 = ?
{17 + β2601}/(? + 2) = 17
- What will come in place of (?), in the given expression.
(12% of 250) + (30% of 400) = ? (7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
2850 ÷ 2.5 - ? × 42 = 300
What will come in the place of question mark (?) in the given expression?
