65 Solution

x	f	Cf
1	8	8
2	10	18
3	11	29
4	16	45
5	20	65
6	25	90
7	15	105
8	9	114
9	6	120
Total	120

Here total frequency = 120

N = 120 = even

⇒ N/2 = 60

In cumulative frequency (C.f.) we select 65 as it is closer to 60.

∴ Median is 5 because 65 is in line of 5.

Solution

Given,

The ratio of incomes of Manish and Pankaj is 11 : 7 and pankaj gets Rs. 6000 less than Manish.

Let the income of Manish and Pankaj be 11x and 7x respectively.

11x - 7x = 6000

⇒ 4x = 6000

⇒ x = 1500

Total income of Manish and Pankaj = (11x + 7x) = 18 × 1500 = Rs. 27000
