The number of chocolate bars that Usha had in the end is repeated. Make the number of chocolate bars that Usha had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Tammy had less than Usha
= 14 u - 3 u
= 11 u
11 u = 132
1 u = 132 ÷ 11 = 12
Number of chocolate bars that Usha had at first
= 14 u
= 14 x 12
= 168
Answer(s): 168
