  2. Tanong 2 ng 18

    Of 60 staff, 45 have finished their training. What percentage have finished?
    Ipakita ang sagot

    Ipakita ang sagot

    Sagot: A. $88

    10% of $80 is $8. New price = 80 + 8 = $88. You can also multiply by 1.10.

  4. Tanong 4 ng 18

    Weekly orders went from 400 to 460. What is the percentage increase?
    Ipakita ang sagot

    Sagot: D. 15%

    Change ÷ starting value × 100: (460 − 400) ÷ 400 × 100 = 15%. Always divide by the starting (base) value.

  5. Tanong 5 ng 18

    Overtime fell from 120 hours to 90 hours. What is the percentage decrease?
    Ipakita ang sagot

    Decrease ÷ starting value × 100: 30 ÷ 120 × 100 = 25%. 33.3% comes from dividing by the new value.

  6. Tanong 6 ng 18

    A team has 12 supervisors and 48 other staff. What is the ratio of supervisors to other staff in its simplest form?

  7. Tanong 7 ng 18

    Ipakita ang sagot

    Sagot: D. 15

  8. Tanong 8 ng 18

    Ipakita ang sagot

    Sagot: C. $6,000

    2 + 1 = 3 parts. One part = 9,000 ÷ 3 = $3,000. Team A gets 2 parts = $6,000.

  9. Tanong 9 ng 18

    The share of customers who were satisfied rose from 60% to 66%. By how many percentage points did it rise?
    Ipakita ang sagot

    Sagot: A. 6 percentage points

    A change in percentage points is a simple subtraction: 66 − 60 = 6 percentage points.

  10. Tanong 10 ng 18

    The share of customers who were satisfied rose from 60% to 66%. What is the percentage increase in the satisfaction rate?
    Ipakita ang sagot

    Sagot: B. 10%

    Percentage change = change ÷ starting value × 100 = 6 ÷ 60 × 100 = 10%. This is different from the 6-percentage-point rise.

  11. Tanong 11 ng 18

    After a 25% discount, a jacket costs $60. What was the price before the discount?
    Ipakita ang sagot

    Sagot: A. $80

    After a 25% discount you pay 75% of the price. Original = 60 ÷ 0.75 = $80. Adding 25% to $60 gives $75, which is wrong because 25% was taken from the original price.

  12. Tanong 12 ng 18

    A bill is $189.00 including 5% tax. What was the amount before tax?
    Ipakita ang sagot

    Sagot: A. $180.00

    The bill is 105% of the pre-tax amount. Pre-tax = 189 ÷ 1.05 = $180.00. Taking 5% off $189 gives $179.55, which is wrong.

  13. Tanong 13 ng 18

    Sales were $5,000 in February. They rose 10% in March, then fell 10% in April. What were April sales?
    Ipakita ang sagot

    Sagot: B. $4,950

    March = 5,000 × 1.10 = $5,500. April = 5,500 × 0.90 = $4,950. The 10% fall is taken from the bigger March figure, so you do not get back to $5,000.

  14. Tanong 14 ng 18

    Ipakita ang sagot

    Sagot: B. 36%

  15. Tanong 15 ng 18

    A cleaning product is mixed 1 part concentrate to 24 parts water. How much concentrate is in 5 litres of mixed solution?
    Ipakita ang sagot

    Sagot: C. 200 mL

    1 + 24 = 25 parts in total. 5 L = 5,000 mL. One part = 5,000 ÷ 25 = 200 mL of concentrate. Dividing by 24 forgets the concentrate itself is a part.

    Ipakita ang sagot

    Sagot: B. 6.0%

    Combine the totals: from $1,000,000 to $1,060,000, a rise of $60,000. 60,000 ÷ 1,000,000 × 100 = 6.0%. A simple average of 10% and 5% ignores that Shop B is much bigger.
