Question

A cyclist, after cycling a distance of 70 km on the second day, finds that the ratio of distances covered by him on the first two days is 4 : 5. If he travels a distance of 42 km. on the third day, then the ratio of distances travelled on the third day and the first day is:

• A. 4 : 3
• B. 3 : 2
• C. 3 : 4
• D. 2 : 3

Answer 1

Answer:

C. 3 : 4

Let the common ratio be x Distance covered in first day = 4x Distance covered in second day = 5x 5x = 70 km X = 14 km Distance covered in first day = 4x = 4×14 = 56 km Distance covered in third day = 42 km Required Ratio = Distance covered in third day/ Distance covered in first day 42/56 = 3 : 4
