The correct answer is C.

Perimeter of each square = 32 cm

Ans 4: (Master Answer)

Admin from revisewise, Noida
Class : Class 1

The correct answer is A.

The order from eldest to youngest is 
M, N or R, Q 
So, M is the eldest.


Ans 5:

ARUNAV from DPS VINDHYANAGAR, VINDHYANAGAR
Class : Class 10
the data is inadequate becuse n can be greater or smaller than m because it is mentioned only that n is not as old as m and also it is not mentioned relationship between r ad n

Ans 6:

Kaira Bhargava from DPS BANGALORE EAST, Bengaluru
Class : Class 5
Answer is not correct.(N) M (N) R (N) Q -> eldest to youngest (left to right)N can be at any these positions.So correct answer is data inadequate.

If we take a as 4 and b as 2, then according to communicative property, 4-2=2 but 2-4=-2 so 2 and -2 are not equal but, if we take a as 4 and b as 4, then it will be 4-4=0 and 4-4=0. Thus, a should be = b
