Correct Answer: 25
Correct Answer: 0
Explanation:
From the given information in the question
24 ÷ 4 + 6 - 3 x 4
6 + 6 - 12 = 0
Correct Answer: 90
Explanation:
Let number of 2 wheelers be 'x'
and 4 wheelers be 'y'
Given total number of vehicles = 200
i.e, x + y = 200 ....(1)
Given total number of wheels = 580
i.e, 2x + 4y = 580 ...(2)
By solving (1)&(2), we get
y = 90
=> x = 110
Therefore, number of two wheelers = 110
number of four wheelers = 90
Correct Answer: 3
Explanation:
Given two lines are parallel
pa+b=2
b=-pa+2..........(1)
3a+b=4
b=-3a+4 ...........(2)
m1 = -p
m2= -3
The condition for the two lines to be parallel is m1=m2
p = 3
Correct Answer: 5
Explanation:
There are total 5 ways.
we have only one kg of weight so,
2kg = 1kg + 1kg
4kg = 1 + 2 + 1
8kg = 1 + 2 + 4 + 1
16kg = 1 + 2 + 4 + 8 + 1
31kg = 1 + 2 + 4 + 8 + 16
So 5 weights are needed.
