Answer 2

question no.12:
-----------------------

let his salary before the increment be 'x'

increment = 20% = 20% of x = ₹0.2x

new salary = ₹30600

x + 0.2x = 30,600

1.2x = 30,600 => x = ₹25,500

Answer: his salary was ₹25,500.

question no. 13 :
-------------------------

attended school = 204 days

his attendance = 85%

85% = 204

1% = 204 ÷ 85 = 2.4

100% = 2.4 × 100 = 240 days

Answer:school was opened for 240 days.

question no.14:
-----------------------

let B's income = ₹100

A's income = 20% less than B's income

A's income = 100 - 20% of 100

= 100 - 20 = ₹80

thus A's income = ₹80

difference = 100 - 80 = ₹20

difference% = (difference × 100)/A's income

= (20× 100)/ 80

= 25%

Answer:
-------------

B's income is 25% more than A's income.
