Correct Answer: 48.88%

Explanation:

Number of runs made by running = 180 - (11 x 4 + 8 x 6)
= 180 - (92)
= 88
Now, we need to calculate 88 is what percent of 180.
? 88 180 × 100  = 48.888%.

Correct Answer: 24.14%

Explanation:

Here 85 of 352 => 85 is what percent in 352

Let p% of 352 is 85

Percentage(%) is generally calculated in the total of 100.

=> p x 352/100  = 85

=> p = 8500/352  = 24.14%

 

Hence, 85 is 24.14% of 352.

 

Correct Answer: 10000

Explanation:

Let his monthly salary be 'P'

20% on children's education =  20 P 100 = P 5

50% on food and transport =  50 P 100 = P 2

1000 on rent

=>  $$\begin{gathered} P - P 5 - P 2 - 1000 = 2000 \\ = > 3 P = 30000 \\ = > P = 10000 \end{gathered}$$

 

Therefore, his monthly salary = Rs. 10,000

Correct Answer: 20%

Explanation:

Let the S.P. be Rs. P Then, C.P. paid by subhash = Rs. (9 x P)/10 S.P. received by subhash = (108% of Rs. P) = Rs. (27 x P) / 25 ∴ Gain = Rs.(27 x P) / 25 - (9 x P) / 10 = Rs. (9 x P) / 50 Hence, Gain% = (9P / 50) x (10P / 9) x 100 % = 20%

Correct Answer: 14.66%

Explanation:

There is no need to use the no of goats i.e (34,398). let initially thete be 1000 goats then 

 

  1000 -----> 1400 -----> 980 -----> 1274 ----->1146.6

 

Thus the % increase = (1146.6-1000)/100 x 100= 14.66%

Correct Answer: 8% excess

Explanation:

Since  Area of Rectangle = side1 x side2
Therefore, error% in area
= x + y + x y 100 %
= [20 - 10 + ( -10 x 20)/100]% or 8%
i.e. 8% excess.

Correct Answer: 24,000

Explanation:

Let K = Kalyan's monthly salary
N = Nandu's monthly salary
S = Sarnesh's monthly salary.
Then from given data,
12% of K = 16% of N
S = N/2 => N = 2S
K = 16/12 x N = 16/12 x 2S
= 16/6 x 1.08/12 = 16/6 x 0.09 = 0.24 lacs = 24,000

Correct Answer: 126%

Explanation:

Suppose total earnings = Rs. 10000
10% saving = 10000 x (10/100) = Rs. 1000
This year 5% more income than prev year = Rs. 10500
12% saving = 10500 x (12/100) = Rs. 1260
Percentage of amount saved = (1260/1000) x 100 = 126%

Correct Answer: 6.709 %

Explanation:

(100-x)%  of 88% of 8400 = 6896

 

=>  100 - x 100 88 100 x 8400 = 6896

=> x = 6.709%

Correct Answer: 4 %

Explanation:

Imension of the duster is assumed as 5x5x7 cm3

Volume of the duster below the water layer
= volume of water increased
= ?xrxrxh = 3.14×52×2.14 ? 168 cm3

Total volume of the duster = 5×5×7 = 175 cm3

Percentage of the duster part below the layer = 168×100/175 = 96%

Percentage of the duster part above the layer = 4%
