San Jay is 2 years younger than Sara. Who is 5 years old than Sasha. San Jay age and Sasha s age total 31. How old is Sara?

Answer 1

j = s -2
so s = j+2

s = sh + 5
so j+2 = sh + 5 or j = sh + 3

j + s + sh = 31

sh+3 + sh+5 + sh = 31
3 sh = 23
sh = 23/3
j = 32/3
s = 38/3 = Sara = 12 years 8 months

Answer 2

lets consume,
sara x,
sanjay x-2,
sasha x-5,
then, sanjay+sara = 31,
i,e (x-2) + (x-5) = 31
2x-7=31
2x= 31+7
x=38/2
x=19
sara is 19 years old.
