Final Price = Initial price + Initial price x 20/100
= Initial price x (1+20/100)
= Rs.300x(1.2)
= Rs.360

Sunil income is less than Mukul  = [(10 / (100 + 10)] × 100 %
= ( 1000 / 110 )%
= 9.09 %

Number of men who can read and write =
150000 × (98 ÷ 100) =147000

Number of men and women who can read and write
=294000 × (53 ÷ 100) =155820

Number of women who can read and write
155820 - 147000 = 8820

Thus, out of 144000 women 8820 can read and write.

Required percentage = (8820 × 100) ⁄ 144000 %=
6.125

(0.756 x 3/4) = (756/1000) x (3/4) x 100 % = 56.7%

90% of A = 30% of B

(90 / 100) * A = (30 / 100) * B

9A = 3B

B = 3A

Given that,

B = x% of A

3A = (x / 100) * A

x / 100 = 3

x = 300.

0.5/100 of A = 85/100
∴ A = Rs. (85 / 0.5) = Rs. 170

Explanation:

Let's first convert both into SI units for better understanding.

x = 30 quintals = 3000 kg
y = 2 metric tons = 2000 kg

Percentage of x/y is calculated by -

x/y % = 3000 / 2000 × 100

x/y % = 150 %

Therefore, 30 quintals are 150 % percent of 2 metric tonnes.

 

Let the number of question be Y.
60% of Y = 12
60Y / 100 =12
Y = 20

Suppose there are 8y questions were asked apart
from the 41 question.Then
37 + 5y/41 + 8y = 80% = 4/5
⇒ 185 + 25y = 164 + 32y
⇒ 7y = 21
⇒ y = 3
∴ Total no. of questions = 41 + 8 x 3 = 65.

Let the number be N.

According to the question,
(78 - 59)% of N = 323
⇒ (19 x N)/100 = 323
∴ N = (323 x 100)/19 = 1700
∴ 62% of 1700 = (62/100) x 1700 = 1054
