a) 1441

b) 4025

c) 1564

d) 1907

The least common multiple of 7 and 5 is 35. Therefore the numbers that you want are the multiples of 35 between 300 and 650.

300 / 35 = 9

650 / 53 = 18

35th multiple after 300 = 315 = 31*9

35th multiple before 650 = 630 = 31*18

So the multiples of 35 in the range of 300 to 650 are 35*9, 35*10, and so on until 35*18. So, 18–9 + 1 (the +1 is to include the last number) gives us 10 numbers.

So total numbers which are divisible by 35 in between 300 & 650 are = 18 – 9+1 = 10.

2/5 work = 1/6 days

1 work = 1/6 * 5/2 = 15 days

Nive’s Full work completed by 15 days

Vino’s 1/6 work completed in 5 days

1/6 work = 1/5 days

1 work = 30 days

Nive + Vino = 1/15 + 1/ 30 = 3/30 = 1/10 days

So they can work together complete the work completed in 10 days.

Total amount = Rs. 11700

Ratio of Pravin, Preti and Priya

½ : 1/3 : ¼

LCM of 2,3,4 = 12

Ratio of Pravin, Preti and Priya = 6: 4: 3

6x + 4x + 3x = 11700

13x = 11700

x = 900

Difference of Pravin and Priya = 6x – 3x = 3x

= 3* 900 = 2700 x + 1/x = 2

A s we can substitute x = 1

x + 1/x = 1 + 1 = 2

x 81 + x 121 = 181 + 1144 = 1 + 1 = 2  Marked price = Rs. X

x * (100/90) * (100/85) = 34425

x = 34425*(100/90) (100/85)

x = 45000

5 years ago average of 4 members = 25

Total age of the family 5 years ago = 25 * 5 = 100

At present total age of the family = 120

At present Total Age of the family including the child = 25 * 5 = 125

Age of the child = 125 – 120 = 5 years

Diameter = 28 cm

Radius = d/2 = 28/2 = 14 cm

Surface area of the sphere = 4πr2

= 4 * (22/7) * 14 * 14 = 2464 cm2

Number of times the keys have to be pressed to type numbers from 121 to 1346
= 3 (999 – 121 + 1) + 4 (1346 – 1000 + 1)
= 3* 879 + 4* (347)
= 2637 + 1388 = 4025
