Class : Class 1

(B):

A. 11 ones + 5 tens = 11 + 50 = 61

B. 20 ones - 6 ones = 20 - 6 = 14

C. 14 ones + 18 ones = 14 + 18 = 32

D. 9 tens - 10 ones = 90 - 10 = 80

Therefore , 14 is the least value among all.

(B):

P = (100 ÷ 2)=50

Q = (800x 1) = 800

R = (40x 2) = 80

S = (2 + 5) = 7

Therefore, P + Q ÷ R x S =50 + 800 ÷ 80 x 7 = 50 + 10 x 7 =50 +70 = 120

(D):

74 x 43 = 3182
Now,
A) 70 x 43 + 4 x 43 = 3182
B) 69 x 43 + 5 x 43 = 3182
C) 72 x 43 + 2 x 43 = 3182
D) 72 x 43 x 2 = 6192
Therefore, 74 x 43 is not equal to 72 x 43 x 2.

(C): After replacing the signs, the given equation becomes,
5 - 16 ÷ 4 + 20 × 40
= 5 - 4 + 20 × 40 = 5 - 4 + 800 = 801
