Question

The sum of five consecutive multiples of 3 is 360. Find these
multiples.​

Answer 1

Solution:

Given – The sum of five consecutive multiples of 3 is 360.

• We have to find out the numbers.

Let the middle number be x. So,

→ First number = x - 6

→ Second number = x - 3

→ Third number = x

→ Fourth number = x + 3

→ Fifth number = x + 6

According to the given condition,

→ Sum = 360

→ (x - 6) + (x - 3) + x + (x + 3) + (x + 6) = 360

→ 5x = 360

→ x = 72

So,

→ First number = x - 6 = 72 - 6 = 66

→ Second number = x - 3 = 72 - 3 = 69

→ Third number = x = 72

→ Fourth number = x + 3 = 72 + 3 = 75

→ Fifth number = x + 6 = 72 + 6 = 78

• Therefore, the numbers are – 66, 69, 72, 75 and 78.

Answer:

• The numbers are – 66, 69, 72, 75 and 78.

ANSWER ✍️

Solution:

Given – The sum of five consecutive multiples of 3 is 360.

• We have to find out the numbers.

Let the middle number be x. So,

→ First number = x - 6

→ Second number = x - 3

→ Third number = x

→ Fourth number = x + 3

→ Fifth number = x + 6

According to the given condition,

→ Sum = 360

→ (x - 6) + (x - 3) + x + (x + 3) + (x + 6) = 360

→ 5x = 360

→ x = 72

So,

→ First number = x - 6 = 72 - 6 = 66

→ Second number = x - 3 = 72 - 3 = 69

→ Third number = x = 72

→ Fourth number = x + 3 = 72 + 3 = 75

→ Fifth number = x + 6 = 72 + 6 = 78

• Therefore, the numbers are – 66, 69, 72, 75 and 78.

Answer:

The numbers are – 66, 69, 72, 75 and 78.
