Explanation
Let as consider MRP = 100
40 % discount = 60
And further 15 % discount = 45
So total discount = 40 +15 = 55 %

Explanation
Ratio of the partnership
A:B:C = 16:14:7
7/37x = 2450
X = 12950

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

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

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

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

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)
