Let assume that 7-2root3 be rational and rational numbers are in the form of p/q form.
We know that root 3 is irrational and not p/q form. It contradicts the statement that it is irrational as it is p/q form.
Subtraction and multiplication of irrational number form irrational number so 7-2root3 is irrational.

E. Postmaster collects money, however partial and delivers the money to Lencho with a note signed as ‘God’.
F. Disappointed Lencho writes a letter to God again to send the money directly to him, because he doesn’t trust the credibility of the Post office officials whom he blames to have stolen 30 pesos.

Lets take assumed mean, A as 16
Class interval =2
∴ui=hxi−A=2xi−16
Now, we have A=16,xˉ=18 and h=2
We know that,
Mean, xˉ=A+h(N1∑fiui)
⇒18=16+2(f+442f+24)
⇒f+442f+24=1
⇒f+44=2f+24
⇒f=20
Hence, the value of missing frequency, f=20

2x+3y=-5 (1)
3x-2y=12 (2)
Add eq 1 and 2 we get
5x+1y=7 (3)
Now
Subtract 1 from 2,we get
X-5y =17 (4)
Multiply 3 by 5 we get,
25x+5y=35 (5)
Now ,
Add 4 and 5 we get,
26x=52
X=2
now ,
Substitute x=2 in eq3
5x+1y=7
5×2+1y=7
10+y=7
y=7-10
y=-3
(x,y)=(2,-3)
