In a party there are male and female members. If 15 female quit then the number of females will become double the number of males. If 45 males quit no. of female becomes five times the number of males. Find the number of females ?

Correct Answer: -4 (1/17)

Explanation:

Given fraction is 5 (2/7) - 3 (1/14) - 2 (1/14) - 1 (1/7) = ? + 3 (1/17) 

It can be written as 

(5 - 3 - 2 - 1) + (2/7 - 1/14 - 1/14 - 1/7) = ? +  3 (1/17) 

-1 + 0 - 3 (1/17) = ?

=> ? = -4 (1/17)

Correct Answer: 20

Explanation:

We know that 

$$\begin{gathered} 40 % = 40 100 = 2 5 \\ ? 2 5 x 24 4 x ? = 48 \\ ? = 48 x 5 x 4 2 x 24 = 20 \end{gathered}$$

Correct Answer: cosx

Correct Answer: 568

Explanation:

142 x 142 x 1 1260 . 25

 

=>  142 x 142 x 1 35 . 5 = 568

Correct Answer: None of these

Explanation:

$$\begin{gathered} 7 8 x 448 + 6 7 x 3374 \\ = > 392 + 2892 \\ = > 3284 \end{gathered}$$

Correct Answer: 36 c

Explanation:

Monday + Tuesday + Wednesday = 37 x 3 -----------(1)
Tuesday + Wednesday + Thursday = 34 x 3---------(2)
Thursday = 4/5 of Monday ------------------(3)
subtract eqn (1) from (2) we get,
Thursday - Monday = -9
=> Monday - Thursday = 9.......(4)
From (3) & (4), we get

So,Thursday = 36 C

Correct Answer: 15.69 cm

Correct Answer: 25

Explanation:

According to BODMAS rule,

After multiplication only, addition is done.

Hence,

5 + 2 x 10 = 5 + 20 = 25.

Correct Answer: p < 12

Explanation:

The given inequality is 3p - 16 < 20

For solving this inequality, follow these steps

Now add 16 on both sides

we get 3p - 16 + 16 < 20 + 16

=> 3p  < 36

Now divide the above eqn with 3 on both sides

we get, 3p/3 < 36/3

p < 12.

Correct Answer: 100

Explanation:

According to BODMAS Rule,

10 + 10(9)

= 10 + 90

= 100
