The normal annual precipitation at stations X, A, B and C are 700 mm, 1000 mm, 900 mm and 800 mm respectively. If the storm precipitation at three station A, B and C were 100 mm, 90 mm and 80 mm respectively, then the storm precipitation for station X will be
A)70mm
B)80mm
C)90 mm
D)105 mm

Question

The storm precipitation at station X can be estimated by observing the pattern in the given data. The storm precipitation at stations A, B, and C is proportional to their normal annual precipitation. The ratios of storm to normal precipitation for A, B, and C are 100/1000, 90/900, and 80/800 respectively, all simplifying to 1/10. Applying the same ratio to station X (700 mm annual precipitation) gives a storm precipitation of 700 mm * 1/10 = 70 mm.
