Ans: C

45% of 750 - 25% of 480

= $${45}/{100} × 750$$ - $${25}/{100 } × 480$$

= 337.50 - 120 = 217.50.

Ans: A

Students failed in Civics = 100 - 65 = 35%

Students failed in History = 100 - 60 = 40%

Students failed in Civics or History = 100 - 40 = 60%

∴ Students failed in both = 35 + 40 - 60 = 15% i.e. 15% = 90

∴ 100% = $${90}/{15} × 100$$ = 600.

Ans: B

60 = ?% of 400

⇒ 60 = $$? × {400}/{100}$$

⇒ 60 = ? × 4

⇒ ? = $${60}/{4}$$ = 15.

Ans: A

Profit % = $$+ 20 - 5 - {20 × 5} / {100}$$ = 15 - 1 = 14%.

Ans: C

Alcohol content in 9 ml shaving lotion of 50% concentration = 9(0.5) = 4.5 ml

To reduce it to 30% concentration, water required = ?

In 30% lotion, alcohol content = 4.5 ml

i.e., 30% quantity = 4.5 ml

∴ 100% quantity = $${4.5} /{30} × 100$$ = 15 ml

∴ Quantity of water in the mixture = 15 - 4.5 = 10.5 ml

Quantity of water now added = 15 - 9 = 6 ml.
