Step-by-step explanation:
Let no. be n
n=7a+1
n=9b+2
n=11c+3
Equations are solvable since only integral solutions are allowed.
11c+3=9b+2
11c+1=9b
b=(11c+1)÷9
put c=1,2...10.at c=4, b=5.
c=13, b=16..... so on
Now look at
11c+3=7a+1
a=(11c+2)÷7
At c=3,a=5
c=10,a=16.... so on.
from first equation, c=9k+4
From second set c=7m +3.
or our first equation
9k+4=7m+3
m=(9k+1)÷7
k=3,m=4....so on
for the lowest possible no.
k=3,m=4
c=31
n=11×31 +3=344.
