Given, total students = 70
M=40; P= 35; C = 30 [Using first alphabet of all subjects]
P+C+M=15
Now, we can solve it by using Venn diagram. Let depict it.
We let the number of students
who study exactly two subjects are x, y & z.
We have to find out the value of (x + y + z)
According to the question
The number of students studying exactly two subjects is 5.

A man's salary in 2014 was 20 thousand Taka per month and it is increased by 10% each year. Find how much he earned in the years 2015 to 2017 inclusive.
His salary in 2014 was 20,000 Tk. per month.
His salary in 2015 was = Tk. per month
100
His total income in 2015 was = Tk.
Again, his salary in 2016 was = Tk. per month
His total income in 2016 was = Tk.
And, his salary in 2017 was = Tk. per month
His total income in 2017 was = Tk.
His total income from 2015 to 2017 was = Tk.
