The mirror image in the following case in

The ratio of number of male workers and female workers in a company is 5:1. If the company has 250 male workers, how many female workers are there in the company? How many more female workers are need to be recruited so that the ratio becomes 1:1?

Girija has a gold coin of 150 gms. She distributed
of the coin to her daughters. Now how much gold is left with Girija?

If of 49 + 20% of 130 is equal to x + 49, then x is
i) 10                    ii) 12
iii) 16                  iv) 18

If    a  then a is

i) 122                               ii) 0
iii) 16 4)                            iv)  -16

If a = 1⁴ ,b = 4⁰ ,c = 0⁴ and d = 4¹, then
1) a = b                  2) b = c
3) a = c                   4) a = d

100- 4[25- (5+12-9)] =
i) - 32                      ii) +132
iii) + 32                      4) -132
