Question

Study the following bar graph carefully and answer the given questions.

The bar graph given below shows the radius (in cm) and height (in cm) of 5 cylinders, i.e., A, B, C, D and E.

By what percent is the sum of the diameters of the five given cylinders more/less than the sum of heights of these five cylinders?

• A. 34.62%
• B. 28.33%
• C. 32.62%
• D. 28.33%

Answer 1

The correct option is A 34.62%

Sum of radius of the five cylinders = 18 + 32 + 42 + 20 + 28 = 140 cm

Sum of the diameters of the five cylinders = 140 × 2 = 280 cm

Sum of heights of the five cylinders = 42 + 70 + 24 + 56 + 16 = 208 cm

Required percentage = $\frac{280-208}{208}\times 100=34.62\%more$

Hence, option A is correct.
