TASK 1

  1. Sold at 800 then reduced to 640, percentage decrease = (decrease)/original price *100%

(800-640)/800*100% = 160/800*100%=20%

  1. Percentage increase from 88 to 92, increase= 92-88= 4

Percentage increase =4/88 *100% = 4.55%

  1. Percentage increase from 2850000 to

Increase = 3100000-2850000 = 250000

% increase =250000/2850000 *100% = 8.77%

  1. After 17% increase 313560, what is last year’s number of laptops shipped?

After increase the % was 17% +100% = 117% which is 313560

If 117% =313560, what about 100%

=100% /117*313560 = 268000

  1. 65 =125% what about 100% ?

100%/125%*65 = 52
