The average temperature of Monday to Wednesday was 37 C and of Tuesday to Thursday was 34 C. If the temperature on Thursday was 4/5 th of that of Monday, the temperature on Thursday was ?

Correct Answer: 175

Explanation:

Let the number of males be 'M'
Let the number of females be 'F'
From the given conditions,
(F-15)=2M.....(i)
F=5(M-45).....(ii)
By solving the equations (1) & (2) we get M = 80
Then substitute M = 80 in (1)
F = 2M + 15
F = 2 x 80 + 15
=> F = 175
Therefore, number of males = 80 and females = 175 in the party.

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: 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

Correct Answer: 2
