SOFTEON Fresher Interview Questions – Part – III
Here in this blog we are discussing about SOFTEON Fresher Interview Questions –
Part – I. Some of them are :
11. If 9x-3y=12 and 3x-5y=7 then 6x-2y = ?
(a) 5 (b) 4 (c) 2 (d) 8
SOLUTION :
On solving 9x – 3y = 12
3x – 5y = 7 we get
9x – 3 y = 12 ———————- (i)
9x – 15 y = 21 ——————— (ii)
12 y = – 9
=> y = -3 / 4
( I ) => 9 x – 3y = 12 => 9x – 3 ( – 3 / 4) = 12
9x + ( 9 / 4 ) = 12
9x = 12 – 9 / 4
9x = (48 – 9) / 4 = 39 / 4
X = 39 / 36
x = 13 /12
Now 6x – 2y = 6 ( 13 / 12 ) – 2 ( – 3/ 4 )
6x – 2y = 13 / 2 + 3 / 2 = 16 / 2
6x – 2y = 8

12 . Successive discounts of 20% and 15% are equal to a single discount of
(a) 30% (b) 32% (c) 34% (d) 35%
SOLUTION :
If the price of an article = Rs. 100
After 20 % discount , the price = Rs. 100 – (100 * 20 / 100) = 100 – 20
= Rs. 80
Again after 15 % discount the price = Rs. 80 – ( 80 * 15 / 100 ) = 80 – 12
= Rs. 68
Hence Discount amount will be Rs. 100 – 68 = Rs. 34
= 34 % of Rs. 100

13 . What is the selling price of a car? If the cost of the car is Rs.60 and a profit of 10% over selling price is earned?
(a) 66 (b) 6 (c) 166 (d) 66.5
SOLUTION :
Cost price of the car = Rs. 60
Profit % = 10 %
=> Profit = Rs. 60 * ( 10 / 100 ) = Rs. 6
Thus , Selling price = Cost price + Profit
= Rs. 60 + Rs. 6
=> Selling Price = Rs. 66

14) If a=2/3b , b=2/3c, and c=2/3d what part of d is b ?
(a) 8/27 (b) 4/9 (c) 2/3 (d) 7/5
SOLUTION :
Given , a = (2/3)b
b = (2/3 )c
c = (2/3)d
Now b = (2/3)c = (2 / 3)(2 / 3)d
= ( 4 / 9 ) d
Hence b : d = 4 : 9 = 4 /9
