72x = 62928 × 100
x =
= Rs.87400
?
32. Option B
?
? = 944 × 59 = 55696
=
? = √ 55696 = 236
33. Option D
Suppose the age of Ranjana and Rakhi is 15x years and 17x years.
After 6 years the age of Ranjana and Rakhi
=
153x + 54 = 150x + 60
153x – 150x = 60 – 54
3x = 6x = 2
So, the age of Ranjana after 6 years = 15 × 2 + 6 = 36 years
34. Option C
Suppose required number is x.
x × = 38

x = 7 × 38

35. Option A
36. Option C
Suppose the length of the field is x m.
So, the breadth of the field will be
m

x ×
= 300
x = √ 400
=
= 400
x = 20
Area of the garden = (20 + 3) (15 + 3) – 300
= (23) (18) – 300 = 114 square metre

37. Option A
10
Suppose the original number is (10x +
9
(10
+ x) – (10x +
+ x – 10x −
= 54
– 9x = 54
– x = 6
– x – 6 = 0
– 3x – 2x – 6 = 0
Original number = 10 × 3 + 3
(x – 3) (x + 2) = 0
x = 3
= 30 + 9 = 39
By Ramandeep Singh
40% of original number = 39 ×
= 15.6
