Answer:

3a

Given,

Mina marks = 450 marks

Mona score was 40 percent higher than mina

So,

Mona marks = 450 +40/100 × 450

= 450+180

= 680

therfore Mona marks are 680

3b

Given,

Monthly salary of a man = 12000

His wife salary is less than him by 20percent

Wife salary = 12,000 - 20/100 × 12000

= 12000 - 2400

= 9600

Total income = 12000+9600

= 21600
