(a) 60 %

(b) 70 %

(c) 50 %

(d) 80 %

Solution: 

(1)

The total number of Huawei smartphone sold in China and Japan together is (140 + 150) thousand = 290 thousand

The total number of Huawei smartphone sold in India and the US together is (130 + 90) thousand = 220 thousand

Option (b) is right.

(2)

 Total number of companies sold by all 5 companies in India is (100 + 150 + 80 + 90 + 100) thousand

= 520 thousand

Average = (520 thousand ÷ 5) = 104 thousand

Option (a) is right.

(3)

Total Samsung smart phone sold in all 4 countries is = (150 + 100 + 150 + 80) thousand

= 480 thousand

Profit on each Samsung phone is 1000 Rs.

Total Profit = (480 thousand x 1000 Rs.)

= 480 million

Option (b) is right.

(4)

Total Smart phones sold by total 5 companies in India is (100 + 150 + 80 + 90 + 100) thousand

= 520 thousand

Total smart phones sold by all 5 countries sold in Japan is (130 + 80 + 60 + 150 + 120) thousand

= 540 thousand

Ratio = 520 : 540 = 26 : 27 

Option (b) is right.

(5)

The number of Samsung smartphones sold in China is 150

The number of Samsung smartphones sold in the US is 100

Option (c) is correct.

(b) 2 : 1

(c) 1 : 2

(d) 3 : 2

(e) None of these

Solution:

(1)

 Total children staying in all the societies together is (56 + 60 + 35 + 48 + 54 + 45) = 298

Option (b) is correct.

(2)

Total number of male staying in all the societies together is (63 + 45 + 42 + 60 + 50 + 65) = 325

Total number of female staying in all the societies together is (48 + 65 + 35 + 64 + 64 + 55) = 331

So, the ratio is 325 : 331

Option (c) is correct.

(3)

Children society A is 56

Male Children : Female Children = 4 : 3

Adult male = 63 – 32 = 31

Adult Female = 48 – 24 = 24

So, ratio is 31 : 24

Option (a) is correct.

(4)

Total children staying in all the societies together is (56 + 60 + 35 + 48 + 54 + 35) = 298

Total female staying in all the societies together is (48 + 65 + 35 + 64 + 64 + 55) = 331

So, difference is (331 - 298) = 33
