Question
In how many months will Rs 8,000 yield Rs 2,648 as
compound interest at 20% per annum compounded semi-annually?Solution
10% P.A Semi annually will be 10% for there Question go through with option 10% of 8000 is 800 as we have given that total intrest 2648, si it is almost 3 times 6 months, 3 times will 18 months or you can find the successive of 10% in 3 semi annually which will 33.1% 8000 × 33.1% = 2648 So Answer is 18 months
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify:

(1/5)(40% of 800 β 120) = ? Γ 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 β 20% of 5280) = ? Γ· 3
β157464 =?
