as i assume the time taken to complete the job is not to be
changed while increasing the employees as it does not
clearly states so……….
30 men wrk for 9 hrs
therefore for the work to be done if no of workers is
increases the no of hrs / day to work should decrease so
here s a inverse relation
solving further we get
30 = K /9 ==> K= 270
now
40 = 270/y ==> y= 6.75
therefore ans is d)none

Suppose 1 person consumes 1 unit food daily.
So, for 24 days, 1600 person will consume 1600×24 units.
So total units of food available = 1600×24

Now total number of person =1200

So, total food will be consumed by 1200 person in (1600×24)/1200 = 32 days.

5*(root2)

40
40
30
60
– 10 cows
+ 20 days
if 40 cows can eat for forty days
then 20 cows can eat for 80 days

50 each
3x -y = 100
4x-2y = 100

90 inches

Slab = 6(x) where x is each step
Slab = 5(x + 3)

6(x) = 5(x + 3)
6(x) = 5(x) + 15
x = 15 inches

So 6(x) = 6(15) = 90

Check: 5( x + 3) = 5(18) = 90

Slab size is 90 inches

He will work for 35 days in 60 days to earn Rs.170 as per the condition

let d distance and s be speed.
d/7 = x and d/5 = x+12
solving we get d=210.
