**Q1. Anil had to do a multiplication. Instead of taking 35 as one of the multiplies, he took 53. As a result the product went up by 540. What is the new product?**

(a) 1050

(b) 540

(c) 1440

(d) 1590

S1. Ans.(d)

Sol. Let the number be x.

Increase in product = 53x – 35x = 18x = 18x = 540 ⇒ x = 30

Hence, new product = 53 × 30 = 1590. Hence, option (d) is the

answer.

answer.

**Q2. What is the least number of soldiers in a regiment, such that they stand in rows of 18, 15 and 25 and also from a solid square?**

(a) 1800

(b) 225

(c) 900

(d) None of these

S2. Ans.(c)

Sol. Number of soldiers should be a multiple of 18, 15 and 25 ⇒

Number should be a multiple of LCM (18, 15, 25)

Number should be a multiple of LCM (18, 15, 25)

Now lowest multiple of 450 that is a perfect square = 900. Hence

option (c) is the answer.

option (c) is the answer.

**Q3. The average weight of 5 apples is 100 g and the average weight of 4 oranges is 80 g. If 2 apples and 2 oranges are picked from them that average weight is found to be 85 g. What is the average weight of the remaining apples and oranges?**

(a) 88 g

(b) 90 g

(c) 96 g

(d) 95 g

S3. Ans.(c)

Sol. Weight of 5 apples = 500 g

Weight of 4 apples = 320 g

Weight of 2 apples and 2 oranges picked = 340 g

So, weight of 3 apples and 2 oranges remaining = (500 + 320 –

340)g = 480 g

340)g = 480 g

Average weight = 480/5 = 96 g

(a) 100

(b) 90

(c) 110

(d) 120

S4. Ans.(a)

Sol. Number of students = (84 – 64) × 94/18.8 = 100

(b) 20%

(c) 33.33%

(d) 16.66%

**Q7. A shopkeeper sells his articles at CP but uses a faulty balance which reads 1000 gm for 750 gms. What is his actual profit percentage?**

(a) 33.33%

(b) 25%

(c) 16.66%

(d) 14.28%

S7. Ans.(a)

Sol. Since while selling, 750 g = 1 kg

So, 250 gms = 1/3 kg

So, profit = 1/3 = 33.33%

**Q8. A seller buys 50 kg oranges for Rs 525 and gains a profit equal to the selling price of 10 kg of oranges. Find the selling price per kg of oranges (Rs/kg).**

(a) 12.60

(b) 11.60

(c) 10.20

(d) 13.125

S8. Ans.(d)

Sol. Assume that the selling price per kg = Rs. X/kg

50X – 525 = 10X ⇒ 40X = 525

So, X = Rs. 13.125 kg

**Q9. The students in three sections of IIML are in the ratio 2 : 3 : 5. If 20 students are increased in each section, the ratio changes to 4 : 5 : 7. The total number of students in the three sections before the increase are-**

(a) 75

(b) 90

(c) 100

(d) 150

S9. Ans.(c)

Sol. Go through the options. Since the sum of ratios = 10, so

**Q10. A bag contains Rs 216 in the form of one rupee, 50 paise and 25 paise coins in the ratio of 2 : 3 : 4. The number of 50 paise coins is:**

(a) 96

(b) 144

(c) 114

(d) 141

S10. Ans.(b)

Sol. Let number of one-rupee coins = 2 K

Number of 50-paise coins = 3 K

Number of 25-paise coins = 4 K

2K × Rs. 1 + 3 K × Rs. 0.5 + 4K × Rs. 0.25 =

Rs. 216

Rs. 216

⇒ 2 K + 1.5K + K = 216

K=48

The number

of 50 paise coins=3K=144

of 50 paise coins=3K=144
