Tabular

Answer :

Total number of cars sold by all the given stores together in Jan = 133 + 161 + 213 + 225 + 282 + 196 = 1210
Total number of cars sold by all the given stores together in April = 178 + 272 + 269 + 284 + 293 + 277 = 1573
Required difference = 1573 - 1210 = 363

Answer :

Total number of cars sold by stores P and R together in March = 278 + 226 = 504
Total number of cars sold by stores T and U together in May = 379 + 237 = 616
Ratio= 504 : 616 = 9 : 11

Answer :

In country H, 80% are post-graduate.

That is = [80/100]*3360 = 2688

Male is given 1800.

Hence, female post-graduate employees = 2688 - 1800 = 888

Total female employees is = [5/14]*3360 = 1200

Hence, required percentage = [888/1200]*100 = 74 Percent

Answer :

Country B = 11:5 à [5/16]*100

Now, let’s say this is approximately 30% (16*3 = 48 which is close to 50).

Country D = [2/5]*100 = 40%

Country E = [6/13]*100 = approx. 45%

Country G = [7/15]*100 = approx. 45%

Country H = [5/14]*100 = approx. 35%

Now, second highest is Country H.

Answer :

Total male employees from countries B and H = [11/16]*2880 + [9/14]*3360 = 1980 + 2160 = 4140

Total female employees from Countries C and D = [11/21]*2310 + [2/5]*3575 = 1210 + 1430 = 2640

Required ratio = 4140:2640 = 69:44.
