A. 31
B. 41
C. 51
D. 61
Explanation:
LCM = 30 => 30 + 1 = 31
A. 10/19
B. 5/9
C. 9/5
D. 19/7
A. Rs.100
B. Rs.700
C. Rs.1600
D. Rs.2000
Let the amount be divided into 7x,4x,3x and 2x.
7x-2x = 500 5x=500 x = 100
Total amount = 7x+4x+3x+2x = 16x = Rs.1600
A. 18/35
B. 12/35
C. 17/35
D. 19/35
Explanation:
If both agree stating the same fact, either both of them speak truth of both speak false.
Probability = 3/5 * 4/7 + 2/5 * 3/7
= 12/35 + 6/35 = 18/35
A. 70%
B. 60%
C. 40%
D. 30%
Explanation:
Total number of employees be 100
Then number of men = 6000/100 = 60
Number of women = 4000/100 = 40
Therefore, number of men drawing more than Rs. 50000 = 2400/100 = 24 men
Since the number of total employees drawing more than Rs. 50000 = 3600/100 = 36
Number of women who draw more than Rs. 50000 = 36- 24 = 12
Number of women who draw less than Rs. 50000 = 40 -12 = 28
Therefore, Percentage of the women who draw less than Rs. 50000 per year = 28/40 x 100% = 70%
A. Increased by 4%
B. decreased by 4%
C. Decreased by 1%
D. Remains unchanged
Explanation:
Let length = x metres and breadth = y metres, then area =(xy)
New length =(120/100x)m = 6x/5 m
New breadth =(80/100 y)m
New area =(6x/5 x 4y/5)m2 = (24/25 xy)m2
Decreased in area =(xy – 24/25 xy)m2= xy/25 m2
Decreased % =(xy/25 x 1/xy x 100)% = 4%
A. 1:6
B. 2:3
C. 4:3
D. 6:1
