Question

If 30% of a number is 1200, then what is the ratio of 40% of the number thus obtained to 40% of 1200?
  1. 10 : 3
  2. 3 : 10
  3. 30 : 15
  4. 20 : 3


Solution

The correct option is A 10 : 3
Given, 30% of a number = 1200
Let the number be 'n'.
30% of n=1200
30100×n=1200
 n = 1200×10030
n = 4000
Hence the number obtained is 4000.
Now,
40% of 4000=40100×4000=1600
Also,
40% of 1200=40100×1200=480
Hence, the required ratio is
=1600:480
=1600480
=103
=10:3
