To complete a work A and B takes 8 days, B and C takes 12 days, A,B and C takes 6 days. How much
time A and C will take | [
"16 days",
"None of these",
"24 days",
"8 days"
] | D | Explanation:
A+B 1 day work = 1/8
B+C 1 day work = 1/12
A+B+C 1 day work = 1/6
We can get A work by (A+B+C)-(B+C)
And C by (A+B+C)-(A+B)
So A 1 day work =
16−112=112
Similarly C 1 day work =
16−18=4−324=124
So A and C 1 day work =
112+124=324=18
So A and C can together do this work in 8 days

"720 m2",
"None",

We have: (l – b) = 28 and 2(l + b) = 120 or (l + b) = 60.
Solving the two equations, we get: l = 44 and b = 16.
Area = (l x b) = (44x 16) m2 = 704 m2.

Mr. Thomas invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in scheme B? | [

(x * 14 * 2)/100 + [(13900 - x) * 11 * 2]/100 = 3508
28x - 22x = 350800 - (13900 * 22)
6x = 45000 => x = 7500
So, sum invested in scheme B = (13900 - 7500) = Rs. 6400.

If the value of a piece of office decreases by 10% while the new tax rate on the office represent 110% of the original tax rate, what is the effect on the taxes? | [
"c- there is no change in taxes",
"a - taxes increase by 10%",
"d- taxes decrease by 1%",
"b- taxes increase by 1%"
] | C | Cansider the value of office = 100, Original tax rate 10%, hence tax value = 100*10% = 10.
Decreased value of office = 90, New tax rate = 110% of 10 = 11%, hence tax value = 90*11% = 9.9
10-9.9 = decrease by 1%.
