If the productivity of a brigade grows by 12% when the number of the workers in the brigade is increased by one, then which of the following is closest to the ratio of the productivity of a 12-person brigade to that of a 10-person brigade? | [
"1.232",
"0.21",
"1.44",
"0.82"
] | A | B = 10-men brigade
p = increase in the productivity = 12%
Solution: B x p = B x 1.12 = 1.12B -------> the productivity of 11 men brigade
1.12B x p = 1.12B x 1.1 = 1.232B -----> the productivity of 12 men brigade
The ratio of the productivity of a 12-men brigade to that of a 10-men brigade = 1.232B/B = 1.232

Daniel went to a shop and bought things worth Rs. 50, out of which 90 Paise went on sales tax on taxable purchases. If the tax rate was 15%, then what was the cost of the tax free items? | [
"B)20",
"A)19.7",
"D)21.5",
"C)43.1"
] | D | Total cost of the items he purchased = Rs.50
Given that out of this Rs.50, 90 Paise is given as tax
=> Total tax incurred = 90 Paise = Rs.90/100
Let the cost of the tax free items = x
Given that tax rate = 15%
∴ (50−90/100−x)15/100 = 90/100
⇒ 15(50 −0.9 −x) = 90
⇒ (50 − 0.9 − x) = 6
⇒ x = 50 − 0.9 − 6
= 43.1

Harold and Millicent are getting married and need to combine their already-full libraries. If Harold, who has 1/2 as many books as Millicent, brings 1/3 of his books to their new home, then Millicent will have enough room to bring 1/3 of her books to their new home. What fraction of Millicent's old library capacity is ... | [

Before:
Assume H = 30 books
H = 1/2 M --> M = 60 books
After:
H' = 1/3H = 10 books
M' = 1/3M = 20 books

In a garment industry, 12 men working 8 hours per day complete a piece of work in 10 days. To complete the same work in 12 days, working 16 hours a day, the number of men required is: | [
"8",
"6",
"5",
"9"
] | C | Explanation :
Let the required number of men be x.
Less days, More men (Indirect Proportion)
More working hrs per day, Less men (Indirect Proportion)
Days 8 : 10
Working Hrs 16: 8 :: 12 : x
=> 12 x 16 x x = 10 x 8 x 12
=> x = 10 x 8 x 12 / (12 x 16)
=> x = 5
