18

Explanation:

Let she had x candy. she took 10 pieces and left over i.e. (x - 10) distributed to her children.

She had 4 children and each child received 2 pieces. Means she had 4 x 2 = 8 candy left over.

Now as per question, (x - 10) = 8

#rArr x - 10 + 10 = 8 + 10# [ adding 10 both sides]

#rArr x = 18#

      @@@ IT CAN BE DONE IN THE FOLLOWING WAY ALSO @@@

She had 4 children and equally distributed the left over to them. Means each will get ( x - 10)/4 pieces.

Now as per question, #( x - 10)/4 = 2#

# rArr(x - 10)/4 xx 4 = 2 xx 4#[ multiply both sides by 4]

#rArr x - 10 = 8#

#rArr x -10 + 10 = 8 + 10#[ adding 10 both sides]

#rArr x = 18#
