Question 41 of 48intermediate🔧 ApplyNumerical3 marks

A frog is at 0. It takes jumps of only 7. What would be the largest number that the frog will reach before crossing 50?

Correct Answer

Given: Frog starts at 0, takes jumps of 7.

Calculation: Multiples of 7: 7, 14, 21, 28, 35, 42, 49 7×77 \times 7 = 49 (less than 50) 7×87 \times 8 = 56 (greater than 50) ∴ The next jump would land on 56, which crosses 50.

Answer: The largest number before crossing 50 is 49.

Explanation

The frog jumps by 7 each time: 0, 7, 14, 21, 28, 35, 42, 49. These are multiples of 7. The next multiple is 56, which is greater than 50. So 49 is the largest number before crossing 50.

Solution Steps

  1. Step 1: Frog jumps by 7: 0, 7, 14, 21, 28, 35, 42, 49...

  2. Step 2: Check multiples of 7 less than 50

  3. Step 3: 7×77 \times 7 = 49 (less than 50)

  4. Step 4: 7×87 \times 8 = 56 (greater than 50)

  5. Step 5: Largest number before 50 is 49
