The simple interest received after 5 years on Rs. (x + 500) at the rate of 20% p.a. is Rs. (2x – 1500). The amount received on Rs. 3x when invested at 40% p.a. compound interest, compounded annually for 2 years can be:
According to the question, {(x + 500) × 5 × 20}/100 = (2x – 1500) Or, x + 500 = 2x – 1500 Or, x = 2000 Therefore, required amount received = 3x × (1 + 40/100)2= Rs. 11760
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
110 ÷ 5.5 + (?)3 ÷ 12 = 20(2/3)
√? = 120 - 102 + ∛125
(√2704 x 55)/(245 + 120) = ?
26 X √25 + 15 - 80% of 120 = ?2
42% of 400 + 38% of 800 + ?2 = 728
3/8 of 720 ÷ 15 + 12 = √?
121/? = ?/144
25% of 12% of 1600 + 112 = ? × 4
