Shopkeeper rise price by 32% and gives successive discount of 10% and 15%. What is overall % gain or loss? | [
"3.95%",
"6.98%",
"4.98%",
"0.98%"
] | D | Let d initial price be 100
32 % rise
now price = 132/100*100 = 132
10% discount
Then price = 132 * 90/100 = 118.8
15 % discount
Then price = 118.8 * 85/100 = 100.98
So Gain = 100.98 - 100 = 0.98
Gain % = Gain * 100 /CP
==> 0.98* 100 /100 = 0.98%

Why do crystals have relatively sharp and well-defined melting points? | [
"angular intermolecular forces",
"uniform intermolecular forces",
"particular intermolecular forces",
"variable intermolecular forces"

A and B together can do a piece of work in 6 days and A alone can do it in 9 days. In how many days can B alone can do it? | [
"21 days",
"22 days",
"12 days",
"18 days"
] | D | Explanation:
A and B can do work 1/6 in 1 day
A alone can do 1/9 work in 1 day
B alone can do (1/6 -1/9) =1/18 work in 1 day
=> complete work can be done in 18 days by B

The length of a rectangle is two - fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units? | [
"675 sq.units",
"169 sq.units",
"196 sq.units",
"140 sq.units"
] | D | Given that the area of the square = 1225 sq.units
=> Side of square = √1225 = 35 units
The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units
Given that breadth = 10 units
Area of the rectangle = lb = 14 * 10
= 140 sq.units

In a company, 48 percent of the employees are men. If 60 percent of the employees are unionized and 70 percent of these are men, what percent of the non-union employees are women? | [
"70%",
"85%",
"65%",
"75%"
] | B | The percent of employees who are unionized and men is 0.7*0.6 = 42%
The percent of employees who are unionized and women is 60 - 42 = 18%
52% of all employees are women, so non-union women are 52%-18% = 34%
40% of all employees are non-union.
The percent of non-union employees who are women is 34%/40% = 85%

Rerty traveled a distance of 30 km, covering the first 10 km in x minutes, the next 10 km in y minutes and the last 10 km in z minutes. If he totally took 3y minutes to cover the whole distance, then which of the following cannot be true? Assume x , y and z are different. | [
"y=3x",
"z=3x",
"x=3z",
"x=2y"
] | D | Rerty Travelled for x,y and for z min.
Total Time : x + y + z
Which is equal to : 3y
Equating both sides we get
x+y+z = 3y
=> x+z =2y ........ Eqn 1
Looking out at options
D Says x =2y
Using it in Eqn 1
2y + z = 2y
=> Z = 0 mins, Which I guess is not possible.
