Dorothy is saving her money for a new bike costing P2860. If she has already saved P39 and is then given P59 for her birthday, how much more does she need to save?

• 2762

• 2267

• 2672

• 2276

Answer explanation

Dorothy has saved P39 and received P59, totaling P98. To find out how much more she needs, subtract her total savings from the bike cost: P2860 - P98 = P2762. Thus, she needs to save P2762 more.

A study of 900 people found that 687 were right handed, 174 were left handed and the remainder were ambidextrous (could use either hand). How many were ambidextrous?

• 63

• 39

• 93

• 36

Answer explanation

To find the number of ambidextrous people, subtract the sum of right-handed (687) and left-handed (174) from the total (900). So, 900 - (687 + 174) = 900 - 861 = 39. Thus, the correct answer is 39.

If William Shakespeare was born in 1564 and lived to be 52 years old, how many years ago did he die?

• 406

• 407

• 408
