विषय: Sharing in a ratio
1. Share £60 in the ratio 2 : 3.
हल
D. £24 and £36
- 2 + 3 = 5 parts, so one part is £60 ÷ 5 = £12.
- 2 parts = £24 and 3 parts = £36.
विषय: Simplifying ratios
2. Write 18 : 24 in its simplest form.
हल
C. 3 : 4
- The highest common factor of 18 and 24 is 6.
- 18 ÷ 6 = 3 and 24 ÷ 6 = 4, so 3 : 4.
विषय: Direct proportion
3. 3 pens cost £2.40. How much do 5 pens cost?
हल
B. £4.00
- One pen costs £2.40 ÷ 3 = £0.80.
- 5 pens cost 5 × £0.80 = £4.00.
विषय: Percentages
4. Increase £80 by 15%.
हल
A. £92
- 15% of £80 = 0.15 × 80 = £12.
- £80 + £12 = £92. Or use the multiplier: 80 × 1.15 = 92.
विषय: Fractions to percentages
5. Write 3/5 as a percentage.
हल
D. 60%
- 3/5 = 3 ÷ 5 = 0.6.
- 0.6 × 100 = 60%.
विषय: Speed
6. A car travels 150 km in 2.5 hours. What is its average speed?
हल
C. 60 km/h
- Speed = distance ÷ time.
- 150 ÷ 2.5 = 60 km/h.
विषय: Units
7. Convert 0.4 kg to grams.
हल
B. 400 g
- 1 kg = 1000 g.
- 0.4 × 1000 = 400 g.
विषय: Recipes
8. A recipe for 4 people uses 300 g of flour. How much flour is needed for 6 people?
हल
A. 450 g
- For 1 person: 300 ÷ 4 = 75 g.
- For 6 people: 6 × 75 = 450 g.
विषय: Reverse percentages
9. A coat costs £45 after a 25% discount. What was the original price?
हल
D. £60
- After a 25% discount the price is 75% of the original.
- 75% = £45, so 1% = £0.60 and 100% = £60.
विषय: Best buy
10. Which is better value: 500 ml for £1.20 or 750 ml for £1.65?
हल
C. The 750 ml bottle
- 500 ml: 120p ÷ 500 = 0.24p per ml.
- 750 ml: 165p ÷ 750 = 0.22p per ml.
- The 750 ml bottle costs less per ml, so it is better value.
