66 students took Sinhala and 22 students took Tamil.
88/100 × 75% = 88×75 = 6600
6600/100 = 66
66 students took Sinhala.
88-66 = 22
22 students took Tamil.

Answer:
sinhala=66 children @75%
tamil=22 children @ 25%
Step-by-step explanation:
let y= children who choose sinhala and
x= children who choose tamil
y+x= 88 children = 100%
therefore
88=100%
y=75%
cross mutiply
y=66
since y+x=88
x=88-66
x=22=25%
