no.of candies mrida has = 2x
according to the question,
x+2x=15
=> 3x=15

Hence no.of candies sinor has= x = 5
no.of candies mrida has= 2x = 2x5 = 10
14). let shabina's son's age be x
shabina's age = 2.5x
according to the question,
2.5x + 10 = 2x
2.5x-2x = 10
0.5x=10
=> x = 10÷0.5
=> x = 20
shabina's age = 2.5x = 2.5x20 = 50yrs
no.of candies mrida has = 2x
according to the question,
x+2x=15

Hence no.of candies sinor has= x = 5
no.of candies mrida has= 2x = 2x5 = 10
