The cost for a business class flight is P20,350. With a budget of P50,000, Joy can afford the flight and will have P29,650 left after the purchase (P50,000 - P20,350 = P29,650).

Richard lives in Manila – he wants to visit Cebu and Davao and return home. He only has P15,000. Can he do it if a ticket from Manila- Cebu is P7500 and Cebu to Davao is another 7500. If so how much will he have left?

Answer explanation

Richard's total travel cost is P15,000 (P7,500 to Cebu + P7,500 to Davao). He has exactly P15,000, so he can make the trip but will have P0 left after returning home.

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.

The crisp factory needs to make 875 bags an hour. If a machine breaks down and the factory only makes 323 bags in one hour, how many does it need to make in the next hour to catch up?

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

• 406

• 407

• 408

• 409

Answer explanation

Shakespeare was born in 1564 and died at 52, which means he died in 1616 (1564 + 52). To find out how many years ago that was from 2024, subtract: 2024 - 1616 = 408. Thus, he died 408 years ago.

In a public telephone booth, 1,234 calls are made before noon and 2,876 calls are made after noon. How many calls were made during the whole day?

• 1,440 calls
