Hello Monish ,
This is simple but little tricky
Let no of engineeers be E, no of MBAs be M , so people who willl be both engineers and MBA will be E
M
People who are not Engineers =32 , so it implies that People who are engineers are 80 – 32=48
Similarly People who are not MBA=56 , implies that people who are MBAs are 80 – 56=24 .
if I denote people who are both engineers and MBA by x
According to the question
People who are both = 2*People who are only MBA
People who are only MBA= total People who are MBA- People who are both MBA and engineer=24-x
substitute :
x=2*(24-x)
x=48-2x
3x=48
x=16
So People who are neither MBA nor Engineers will be =
80 -(total Enginners +total MBAs- who are both )=80 -(48+24-16)=80-56=24 ..
answer is 24
Please make a venn diagram clarity will be much better , let me know if any doubt !
