A bag contains 4 vivo mobiles, 6 Lenovo mobiles and 5 oppo mobiles. 3 mobiles are drawn at random. What is the probability of choosing at least one is oppo mobile?
Correct
Answer: d)
Total probability = 15C3
Required probability = 1- none is oppo mobile
The probability of choosing none is oppo mobile,
= > 10C3/15C3 = (10*9*8)/(15*14*13)
= > 24/91
Probability of choosing at least one is oppo mobile,
= > 1 – (24/91) = 67/91
Incorrect
Answer: d)
Total probability = 15C3
Required probability = 1- none is oppo mobile
The probability of choosing none is oppo mobile,
= > 10C3/15C3 = (10*9*8)/(15*14*13)
= > 24/91
Probability of choosing at least one is oppo mobile,
= > 1 – (24/91) = 67/91
Question 13 of 20
13. Question
A man purchases 2 watches for Rs. 665. He sells one of them at 20% profit and another at 15% loss. Thus, he neither gains nor loses. Find the selling price?
Correct
Answer: a)
CP1 + CP2 = 665
=> 3 : 4
7’s =665 = > 1’s = 95
CP1 = 95*3 = 285
CP2 = 95*4 = 380
SP1 = 285*(120/100) = Rs. 342
SP2 = 380*(85/100) = Rs. 323
Incorrect
Answer: a)
CP1 + CP2 = 665
=> 3 : 4
7’s =665 = > 1’s = 95
CP1 = 95*3 = 285
CP2 = 95*4 = 380
SP1 = 285*(120/100) = Rs. 342
SP2 = 380*(85/100) = Rs. 323

= > 15 women + 10 women + 15 women = 40 women
Women days hours
5 75 8
40 ? 10
(5*75*8) = (40* x days *10)
X = 7 ½ days
Incorrect
Answer: d)
4 men = 5 women
5 women = 6 boys
12 men and 10 women and 18 boys
= > 15 women + 10 women + 15 women = 40 women
Women days hours
5 75 8
40 ? 10
(5*75*8) = (40* x days *10)
X = 7 ½ days
Question 15 of 20
15. Question
A boat can cover 15 km downstream in 45 minutes. If the speed of the current is ¼ of the boat in still water, then how much distance can the boat cover upstream in 66 minutes?
Correct
Answer: a)
The speed of downstream= D/T = 15/(45/60) = 20 km/hr
The speed of the current = ¼ of the boat in still water
Speed of boat : Speed of Current = 4 : 1 = (4x: x)
Speed of downstream = Speed of boat + Speed of Current = 5x
20 = 5x
X= 4
Speed of boat = 16 km/hr, Speed of Current = 4 km/hr
Speed of upstream= Speed of boat – Speed of Current = 3x
Speed of upstream = 12 km/hr
Time = 66 min= (66/60) hr
Distance= S*T = 12*(66/60) = 13.2 km
Incorrect
Answer: a)
The speed of downstream= D/T = 15/(45/60) = 20 km/hr
The speed of the current = ¼ of the boat in still water
Speed of boat : Speed of Current = 4 : 1 = (4x: x)
Speed of downstream = Speed of boat + Speed of Current = 5x
20 = 5x
X= 4
Speed of boat = 16 km/hr, Speed of Current = 4 km/hr
Speed of upstream= Speed of boat – Speed of Current = 3x
Speed of upstream = 12 km/hr
Time = 66 min= (66/60) hr
Distance= S*T = 12*(66/60) = 13.2 km

Direction (1-5):
1) Answer: d)
(2/5)*(40/23)*3588 = (34/100)*2500 + (4/7)*x
2496 – 850 = (4x/7)
1646*(7/4) = x
x = 2880.5
2) Answer: a)
X = 9675 ÷ 45 + 572 + (1/8)* 1680
X = 215 + 3249 + 210
X = 3674
3) Answer: c)
(43/200)*6800 + (37/300)*7800 = (7/9)* 1080 + x
1462 + 962 – 840 = x
X = 1584
4) Answer: b)
2145*(28/5)*(275/11)*(72/11232) = x
X = 1925
5) Answer: b)
(∛2744)2 ÷ (∜38416)3 × x = (√14)5
142 ÷ 143 × x = (√14)5
