Hira has 30 bangles, 18 of which are pink and 12 of which are white. Saher has 20 bangles, all of them either pink or white. If the ratio of the pink bangles to the white bangles is the same for both Hira and Saher, then Hira has how many more pink bangles then Sahar?

Hira bangles ratio :

pink: white

18: 12

3:2

Saher are also with the same ratio as Hira

pink :white Total

3:. 2: 20

3 x + 2 x = 20 => 5 x 20 => X = 4

3 X = 3 (4 )= 12 pink bangles

Hira have: 18 - 2 = 6 bangles more than Sahar.

So last no 3

In the division calculation 952 473 Ã· 18, which two adjacent digits should be swapped in order to increase the result by 100?

If after division by 18 the number has to be increased by 100, then before the division it needs to be increased by 18 Ã— 100 = 1800. So we need to find two adjacent digits in the number 952 473 which when swapped increase it by 1800. If 952 473 is increased by 1800 it becomes 952 473 + 1 800 = 954 273. We obtain 954 273 from 952 473 by swapping the adjacent digits 2 and 4.

A car travels first half distance between two places with a speed of 40 kilometre per hour and rest of half distance with a speed of 60 km per hour. The average speed of car is:

Let the total distance covered be"s" km.

Total time taken,

=(s/2)/30+(s/2)/60

=3s/120

Average speed,

=s/(3s/120)

=s(120/3s)

=40 km/hr
