Question

Regina had 84 more ribbons than Sally. After giving Sally some of her ribbons, Regina then had 1/5 as many ribbons as Sally. How many did Regina have at first?

Answer

After :
Regina : 1 unit
Sally : 5 units
Total : 6 units

At first —
Regina : 1 unit + 84
Sally : 1 unit
Total : 2 units + 84

6 units = 2 units + 84
1 unit = 84/(6 – 2) = 21
1 unit + 84 = 21 + 84 = 105

Ans : 105 ribbons.
