Quick parse - a typical math numerical. The data on the table: 21 cm, 2640 cm. We are after How many revolutions does a wheel of radius 21 cm make to cover 2640 cm (pi = 22/7)?. Tool of choice - hence the answer = 20. Rearrange it for the unknown before substituting. Numbers in: hence the answer = 20. Common-sense check: draw the relevant radii and use the fact that the tangent _|_ radius at the contact point. Lock in option B) 20. Trap-watch: option A) '132' doesn't hold - Wrong: uses an incorrect intermediate value; option C) '21' is wrong because Wrong: a step was skipped or HCF/LCM swapped.
