Question
The simple interest received on a certain sum is Rs. 400
less than the sum invested. If the sum was invested at 15% p.a. for 5 years, then find the simple interest received.Solution
Let the sum invested be Rs. x Therefore, simple interest received = Rs. (x – 400) According to the question, {(x × 15 × 5)/100} = x – 400 => 0.75x = x – 400 => 0.25x = 400 => x = 400/0.25 = 1600 Therefore, simple interest received = x – 400 = 1600– 400 = Rs. 1200
1242.12 ÷ √530 + 1139.89 ÷ 14.91 = ? + 45.39
? = 25.08 + 11.99 × 24.07
40 × 55.96 ÷ 7 – 20% of 699.81 + 63 = ? - (11479.50 ÷ 7)
25.902 × 78.095 + 999.996% of 200.08 + 20.005 % of 7999.997 = ? × 15.008 × 33.009
11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.272
78% of 1450 + 26² = ? + 1323 ÷ 17
