Simplify the fraction? 5 (2/7) - 3 (1/14) - 2 (1/14) - 1 (1/7) = ? + 3 (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: 10

Explanation:

1 7 x 1 2 x 1 9 . 5 x 1 2 x 2660 = 2660 266 = 10

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: 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.
