There are 168 sweets altogether
Solution:
Richard, Henry and Gavin share some sweets in the ratio 5 : 4 : 3
Let "5a" be the share of Richard
Let "4a" be the share of Henry
Let "3a" be the share of Gavin
Richard gets 70 sweets
share of Richard = 70
5a = 70
a = 14
To find: number of sweets altogether
number of sweets altogether = share of richard + share of henry + share of gavin
number of sweets altogether = 5a + 4a + 3a
number of sweets altogether = 12a = 12(14) = 168
Thus there are 168 sweets altogether
