Question: Find the value of P + Q - R - T + S, where P = 3.57, Q = 42.21, R = 8.7, S = 5.34 and T = 2.31.


A ) 56.79
B ) 11.01
C ) 51.12
D ) 40.11

Steps to derive

4 P + Q - R - T + S

5 = 3.57 + 42.21 - 8.7 - 2.31 + 5.34

6 = (3.57 + 42.21) - (8.7 + 2.31) + 5.34

7 = 45.78 - var2 + 5.34
 [Simplify.]

8 = (45.78 + 5.34) - var2
 [Use associative property.]

9 = var3 - var2 = var4
 [Simplify.]

10 P + Q - R - T + S = 40.11



Hence the right answer is Option D
