Question

If Cosmo buys 2 more candies he will have 6 times 7 candies. He arranges the candies in an array with 8 rows. How many columns will be there in the array?

• A. $7$
• B. $5$
• C. $4$
• D. $6$

Answer 1

The correct option is B $5$

• Number of candies Cosmo will have if he has 6 times 7 candie

= 6 times 7
= 6 $\times$ 7
= 42

• Now, 42 is 2 more than what Cosmo has.
• Therefore, number of candies Cosmo has = 42 $-$ 2 = 40
• Cosmo arranges 40 candies in 8 rows.
• We have to calculate the number of candies in each row.
• The multiplication equation will be, No. of rows $\times$ No. of candies in each row = Total candies
• Let’s take the number of candies in each row as “s”. 8 $\times$ s = 40

Since 8 $\times$ 5 = 40, s = 5

• Therefore, there will be 5 columns of candies or 5 candies in each of the 5 rows.
• Hence, option A is correct
