Let their ages 10 years ago is x, 2x and 3x years.
(x + 10) + (2x + 10) + (3x + 10) = 90 hence x= 10
B's present age = (2x + 10) =30 years.

53. Cost of an item is x. It's value increases by p% and decreases by p% Now the new value is 1 rupee, what is the actual value ?

Explanation:

Given cost of an item = Rs. X
Item cost by increasing p% will be = x(100+p)/100
After p% decrement, value = {x+(xp/100)}-[{x+(xp/100)}p/100]
= [x+(xp/100)] [1-(p/100)]
= x[1+(p/100)][1-(p/100)]
Givne new value is 1
x[1-((p^2)/10000)] = 1
x = 1/[1-((p^2)/10000)] = 10000/[10000-(p^2)]

55. A man traveled from the village to the post-office at the rate of 25 kmph and walked back at the rate of 4 kmph. If the whole journey took 5 hours 48 minutes, find the distance of the post-office from the village.

Explanation:

Average speed = (2*a*b)/(a + b) here a = 25 b = 4
Average speed = 2*25 * 4/(25 + 4) = 200/29 kmph.
Distance covered in 5 hours 48 minutes = Speed * time
Distance = (200/29)*(29/5) = 40 kms
Distance covered in 5 hours 48 minutes = 40 kms
Distance of the post office from the village = (40/2) =20 km.

57. Three friends Gerard, Rooney and Ronaldson work together to dig a hole. Gerard alone can complete the work in 10 days, Rooney in 8 days and together all three can complete it in 4 days. They earn a total of Rs. 1,200. Find the share of Rooney if the money that they receive is proportional to the work that they do?

Explanation:

Ronaldson can complete work in 40 days ( 1/4-1/10-1/8)
So, ratio of work done = 1/10 :1/8 : 1/40 = 4 : 5 : 1
So, amount payed rooney = 1200 * (5 / (5+4+1) ) = 1200 * 1/2 = 600

So, Rooney share = 1200/2 = 600

59. The product of two positive numbers is p. If each of the numbers is increased by 2, the new product is how much greater twice the sum of the two original numbers?

Explanation:

Lets assume number are x,y
So, there product = xy
Given number increased by 2
so, now number are x+2,y+2.
Given product is twice the sum of two original No.
=> product = (x+2)(y+2) = 2(x+y)
=> xy+2x+2y+4 =2(x+y)
=> xy+4
so it increase by 4

60. The price of a jewel, passing through three hands, rises on the whole by 65%. If the first and second sellers earned 20% and 25% profit respectively, find the percentage profit earned by the third seller.

Explanation:

Lets assume the original price of the jewel = Rs. P
and profit earned by the third seller= x%.

Then, ( 100 +x )% of 125% of 120% of P = 165% of p
=> [ ( 100+x )/100*125/100*120/100* P ] = [ 165/100* P ]
=> ( 100 + X ) = (165*100*100)/(125*120) = 110,
=> X = 10%.
