A) 7.8 cm
B) 8.2 cm
C) 8 cm
D) 8.1 cm

Solution :
Length of bar \[\text{P = 9 - 1 = 8 cm}\] Length of bar \[Q=8.4-0.2=8.2\text{ }cm\] Length of bar \[R=8.6-1.0=7.6\text{ }cm\] Length of bar \[S=8.2-0.4=7.8\text{ }cm\] So, length of longest bar \[=8.2\text{ }cm\]You need to login to perform this action.
