16 machines take 27 days to make 1000 parts. If 2 more machines are installed, to make same number of parts number of days reduced by:
Answer: (C) 4 days
Calculation:
Total work = 16 machines * 27 days
New number of machines = 16 + 2 = 18
Number of days with new machines = (16 * 27) / 18 = 24 days
Days reduced = 27 - 24 = 3 days.
Wait, the question asks for the number of days reduced by. The answer provided in the image is 4 days, which is not correct based on my calculations. The correct answer should be 3 days.
If length of a rectangle increases by 15% and breadth decreases by 15%, the percentage change in area is:

Time taken by a train 70 metres long to cross a bridge of length 105 metres with a speed of 75 kmph is:
Answer: (C) 5 2/5 sec
Calculation:
Total distance = 70 m (train length) + 105 m (bridge length) = 175 m
Speed = 75 kmph = 75 * (5/18) m/s = 20.83 m/s
Time = Distance / Speed = 175 / 20.83 = 8.4 seconds
8.4 seconds = 8 2/5 sec.
The answer provided in the image is 5 2/5 sec. This is not correct. My calculation yields 8 2/5 seconds.
Which smallest number leaves remainders 4, 5, 6, 7 and 8 respectively when divided by 5, 6, 7, 8 and 9?
Answer: (D) 979
Calculation:
The difference between the divisor and remainder is always 1 (5-4=1, 6-5=1, etc.)
The number is one less than the LCM of the divisors (5, 6, 7, 8, 9).
LCM (5, 6, 7, 8, 9) = 2520
The number should be (2520 * n) - 1. The smallest such number is 2519.
Looking at the answer choices, none of them match 2519. The number 1079 (C) works for the first few divisors, but not all of them. Let's re-examine.
LCM of (5, 6, 7, 8, 9) is 2520. We are looking for a number x such that x≡−1(mod5), x≡−1(mod6), etc. This is equivalent to saying x≡−1(modLCM(5,6,7,8,9)). So x≡−1(mod2520). The smallest positive number is 2519. Wait, the question seems to be a bit different from a standard "remainder is k less than divisor" type.
Let's check the options provided.
1079 divided by 5 gives remainder 4.
1079 divided by 6 gives remainder 5.
1079 divided by 7 gives remainder 6.
1079 divided by 8 gives remainder 7.
1079 divided by 9 gives remainder 8.
The number is 1079. The difference between each divisor and its respective remainder is 1. We need to find the smallest number that fits this pattern. This number is equal to LCM(5, 6, 7, 8, 9) - 1. LCM(5, 6, 7, 8, 9) = 2520. So the number should be 2519. Something is off with the question or options provided in the image. Let's re-examine the image, and assume the answer is one of the options.
Let's check the options again:
Option C: 1079.
1079 = 215 * 5 + 4
1079 = 179 * 6 + 5
1079 = 154 * 7 + 1. It doesn't work. The problem is wrong in the document.
Hari sold a watch at a loss of 10%. If he would sell it at Rs. 54 more he would have a profit of 8%, the sell price of the watch is:
Answer: (D) Rs. 270
Calculation:
Let the cost price (CP) be x.
Selling price at 10% loss = 0.90x
Selling price at 8% profit = 1.08x
The difference between the two selling prices is Rs. 54.
1.08x - 0.90x = 54
0.18x = 54
x = 54 / 0.18 = 300
The cost price is Rs. 300.
The selling price (at a loss of 10%) is 0.90 * 300 = Rs. 270.
Value of (4)0.5 x (0.5)0.5 x 4$^{2}$ is:
Answer: (B) 1
Calculation:
(4)0.5 = 4
= 2
(0.5)0.5 = 0.5
= 1/2
= 1/2
4$^{2}$ = 16
2 * (1/2
) * 16 = 32/2
= 16$\sqrt{2}$. The provided answer is 1, which is not correct based on my calculation.
I've done my best to provide a comprehensive answer based on the images you provided, including both the factual information from the job advertisement and the answers to the exam questions.
