1.Answer – 3) 55%

Explanation

Let as consider MRP = 100

40 % discount = 60

And further 15 % discount = 45

So total discount = 40 +15 = 55 %

2.Answer – 2) Rs. 12950

Explanation

Ratio of the partnership

A:B:C = 16:14:7

7/37x = 2450

X = 12950

3.Answer – 2) 4

Explanation :

Urmila takes 21 days for complete work

Time taken by Anand of complete work = 21× 100/150 = 14days

Let total work is LCM of 14 and 21 = 42

Per day work of Urmila = 42/21 = 2

Per day work of Anand = 42/14 = 3

They both together worked for 6 days

Hence work done in 6 days = 6× (2+3) = 30

Work which anand did alone = 42-30 = 12

Anand worked alone for 12/3 = 4 days

4.Answer – 1) 24

Explanation

16 x .5 = 8

8 x 1 = 8

8 x 1.5 = 12

12 x 2 = 24

24 x 2.5 = 60

5.Answer – 2) x < y

Explanation

X = 6, 5

Y= 8, 7

6.Answer- 5) 650

Explanation- Total number of laptops sold by company A = 7600

Average number of laptops sold by company A= 7600/4 = 1900

Total number of laptops sold by company C = 1250

Required difference = 1900 – 1250 = 650

7.Answer- 2) 100/17 % less

Explanation: Average number of laptops sold by company A in July, August and September = (1500 + 1800 + 2300)/3 = 5600/3

Average number of laptops sold by company B in August, September and October = (1600 + 1850 + 2500)/3 = 5950/3

Difference = 5950/3 – 5600/3 = 350/3

Required percentage = 350/3/5950/3×100 = 100/17 % less

8.Answer- 2) 29%

Explanation:

Total sale in July = 1500 + 2400 + 800 = 4700

Total sale in October = 2000 + 2500 + 1550 = 6050

Required percentage = (6050 – 4700)/4700×100 = 29% (approximately)

9.Answer- 1) 2320

Explanation- laptops sold by company B in November= 2500 + 30% of 2500 = 3250

Required average = (3250 + 2500+1850 + 1600 + 2400)/5 = 2320

10.Answer- 1) August

Explanation- percentage increase in August from July = 400/800×100 = 50%

Percentage increase in September from August = 250/1200×100 = 20.83%

Percentage increase in October from September = 100/1450×100 = 6.8%

Therefore, the percentage increase in August from July is maximum.
