42. Three friends divided some bullets equally. After all of them shot 4 bullets the total no.of remaining bullets is equal to that of one has after division. Find the original number divided
Answer: 18
Explanation:Lets assume no. of Bullets = x
There are 3 divided equally each have x/3 bullets.
So, 4 bullets shot By each the no of bullet shoted is 4*3=12
=> remaining bullet = the bullet of a person
x-12=x/3 => 3x-36=x => 2x=36
=> x=18

44. A man sold two cows for Rs. 210 at a total profit of 5 %. He sold one cow at a loss of 10% and another at a profit of 10%. What is the price of each cow?
Answer: Rs. 150 & Rs. 50
Explanation:Total 5% profit on Rs.210 i.e. Original Price= Rs. 200
Lets assume one cow price = Rs. x
so another cow price = Rs. (200-x)
Now loss of 10% on X = 10x/100
& profit of 10% on (200-x) =(200-x)10/100
=> x-[10 x /100] + [200 - x]+[(200 - x)10/100]=210
By Solving this x = 50
so one cow is of x = Rs. 50
and Other is of 200-x = (200-50) = Rs. 150

45. A family I know has several children. Each boy in this family has as many sisters as brothers but each girl has twice as many brothers as sisters. How many brothers and sisters are there?
Answer: 4 boys and 3 girls.
Explanation:Lets assume no. of girls = x and boys = y
y = (x+1) ----------- (i)
As each boy have equal no. of sisters and brothers and he is not included in brothers.
so, 1 is for him in (x+1).
y = 2(x-1) ------ (ii)
as each girl have (x-1) sisters.
By solving eq. (i) and(ii)
girls = 3 and boys = 4

46. In a soap company a soap is manufactured with 11 parts. For making one soap you will get 1 part as scrap. At the end of the day u have 251 such scraps. From that how many soaps can be manufactured?
Answer: 25
Explanation:251 scraps will be used to make 22 soaps with remaining 9 scraps. again the 22 soaps will produce 22 scraps.
so 22+9=31 scraps which makes 2 soaps with remaining 9 scraps. Again the 2 soaps will produce 2 scraps.
=> we have 11 scraps which can be used to make 1 soap with 1 scrap as remaining.
Therefore totally,22+2+1=25 soaps.

47. There is a 5 digit no. 3 pairs of sum is eleven each. Last digit is 3 times the first one. 3 rd digit is 3 less than the second.4 th digit is 4 more than the second one. Find the digit.
Answer: 25296
Explanation:Let the 5 digit no as "a b c d e"
Given last digit is 3 times first => e=3a
3rd digit 3 less than second => c = (b-3)
4th digit is 4 more than second => d = (4+b)
Now a,b,(b-3),(4+b),3a
Given, 3 pairs of sum is 11
so, c+d = 11 ---- (1)
=> b-3+b+4=11 => b = 5
c = 2, d = 9
so number is __529__
we have think of a number which should be added to five to get 11
5+6=11
So, last no (i.e e) = 6
a = 2
So, number is 25296

48. Every day a cyclist meets a train at a particular crossing. The road is straight before the crossing and both are traveling in the same direction. The cyclist travels with a speed of 10 Kmph. One day the cyclist comes late by 25 min. and meets the train 5km before the crossing. What is the speed of the train?
Answer: 60 kmph.
Explanation:Speed of the train = 60km/hr.
Speed of Cyclist travel = 10km/hr.
It means, Cyclist travels 5km in 30minutes.
If Cyclist comes late by 25 min and meets the train 5km before the crossing means, it shows
Train can travel 5Kms in 5minutes.
So, speed of train is (5 km/5min) = 1 km/1min = 60km per hour.
