  1. What is the LCM of 12, 18, and 24?

    Answer: 72

    Prime factorizations give LCM = 2³ × 3² = 72.

  2. If a boat travels 15 km upstream in 3 hours and 15 km downstream in 1.5 hours, what is the stream's speed?

    Answer: 2.5 km/h

    Upstream speed = 5 km/h; downstream speed = 10 km/h; stream speed = (10−5)/2 = 2.5 km/h.

  3. A vendor sells 40 pens for the cost price of 50 pens. What is the profit percentage?

    Answer: 25%

    SP of 40 = CP of 50; profit on 40 = CP of 10; profit % = 10/40 × 100 = 25%.

  4. A sum of money becomes 3 times in 8 years at simple interest. In how many years will it become 5 times?

    Answer: 16 years

    Rate = 200/8 = 25%; to become 5 times, need 400% interest; time = 400/25 = 16 years.

  5. The HCF of two numbers is 12 and their LCM is 360. If one number is 60, what is the other?

    Answer: 72

    Other number = (HCF × LCM) / first number = (12 × 360) / 60 = 72.

  6. A mixture of 60 liters has milk and water in ratio 2:1. How much water must be added to make ratio 1:1?

    Answer: 20 liters

    Milk = 40L, water = 20L; to make 1:1 with 40L milk, need 40L water; add 20L.
