27Prepared by :
V + 2x – (A-2x) = 30 = V – A + 4x = 30 ……………… (2)
Substituting f + d as m + 15 in (1),
From (1) we have V - A = 2x
we get 2m + 15 = 105
Substituting V – A = 2x in equation (2)
2m = 90 =m = 45 years
6x = 30 = x = 5.
40. Total distance travelled = 1800 km
38. Let the price of book be y and price of pen be x.
Distance travelled by plane = 600 km
x + 2y = 70
Let distance travelled by bus = x
3x + 9y =300
By solving the equations we get x = 10 and y = 30
Distance travelled by train = 3x/5
The difference between the cost of book and pen is 30
x + 3x/5+ 600=1800
– 10 = Rs. 20
39. Let the present age of the father, mother and
8x/5=1200=x=750 km
daughter be f, m and d respectively.
(f+m+d)/3=35
76. Number of ways = 2 × 4! = 48
f + m + d = 105 …………………….. (1)
80. Required time =
× 100 = 37.5 min.
m + 15 = f + d
