Question

Match the following List-I with List-II and select the correct answer using the codes given below the lists :

$\begin{array}{cc}\text{List-I (Measuring Instruments)}& \text{List-II(Application)}\\ \text{P. Auto collimator}& \text{1. On-line measurement of moving parts}\\ \text{Q. McLeod gauge}& \text{2. T-slots}\\ \text{R. Laser scan Micrometer}& \text{3. Flatness}\\ \text{S. Transfer calipers}& \text{4. Vacuum}\end{array}$

• A. P-2, Q-4, R-1, S-3
• B. P-3, Q-2, R-1, S-4
• C. P-2, Q-4, R-3, S-1
• D. P-3, Q-4, R-1, S-2

Answer 1

The correct option is D P-3, Q-4, R-1, S-2

$\text{Auto collimator}\to \text{Flatness}$

$\text{McLeod gauge}\to \text{Vacuum}$

$\text{Laser scan Micrometer}\to \text{On-line measurement of moving parts}$

$\text{Transfer calipers}\to \text{T-slots}$
