What is the total number of post graduates in departments B and C, if ratio of graduates to post graduates in department B is 7 : 2 and total employees in department C is 33 1/3% more than employees in department B?

Correct

Explanation:
employees in department C = [(100 + 100/3)/100] * 270 = 360
Post grads in B + post grads in C = (2/9)*270 + (7/12)*360 = 60 + 210

Incorrect

Explanation:
employees in department C = [(100 + 100/3)/100] * 270 = 360
Post grads in B + post grads in C = (2/9)*270 + (7/12)*360 = 60 + 210

If employees in department C is 10% less than employees in department E and ratio of graduates to postgraduates in department A is equal to the ratio of employees in departments C and A, then total graduates in department C is what percent of total post graduates in department A?

Correct

Explanation:
employees in department C = 90/100 * 400 = 360
ratio of grads to post grads in A = 360/450 = 4 : 5
So Grads in C = (5/12)*360 = 150, post grads in A = (5/9)*450 = 250
So required % = (150/250)*100

Incorrect

Explanation:
employees in department C = 90/100 * 400 = 360
ratio of grads to post grads in A = 360/450 = 4 : 5
So Grads in C = (5/12)*360 = 150, post grads in A = (5/9)*450 = 250
So required % = (150/250)*100

The number of employees in department C is 360 and number of females in same department is 30 less than the number of females in department B. What is the ratio of total number of males in departments B and C to that of the total number of females in departments A and D?

Correct

Explanation:
Number of females in C is 4/9 * 270 – 30 = 90
So males in C = 360 – 90 = 270
Males in B + males in C = (5/9)*270 + 270 = 150 + 270 = 420
Females in A + females in D = (7/15)*450 + (5/11)*220 = 210 + 100 = 310
42 : 31

Incorrect

Explanation:
Number of females in C is 4/9 * 270 – 30 = 90
So males in C = 360 – 90 = 270
Males in B + males in C = (5/9)*270 + 270 = 150 + 270 = 420
Females in A + females in D = (7/15)*450 + (5/11)*220 = 210 + 100 = 310

If the ratio of graduates to post graduates in department E is equal to the ratio of employees in department A to employees in department B and number of males in department E is 120, then how many post graduate females are there in department E?

Correct

Explanation:
in E, females are 400-120 = 280,
ratio of graduates to post graduates in department E = 450 : 270 = 5 : 3 so total postgrads in E = (3/8)*400 = 150, but we are not given grads to postgrads ratio in females.

Incorrect

Explanation:
in E, females are 400-120 = 280,
ratio of graduates to post graduates in department E = 450 : 270 = 5 : 3 so total postgrads in E = (3/8)*400 = 150, but we are not given grads to postgrads ratio in females.

If ratio of graduates to post graduates in department B is 119 : 34 and ratio of graduates to post graduates in department E is equal to the ratio of employees in department A to employees in department B, then what is the number of total graduates in the company?

Correct

Explanation:
ratio of graduates to post graduates in department B is 119 : 34 = 7 : 2
ratio of graduates to post graduates in department E = 450 : 270 = 5 : 3 so
(4/9)*450 + (7/9)*270 + (5/12)*360 + (1/2)*220 + (5/8)*400

Incorrect

Explanation:
ratio of graduates to post graduates in department B is 119 : 34 = 7 : 2
ratio of graduates to post graduates in department E = 450 : 270 = 5 : 3 so
(4/9)*450 + (7/9)*270 + (5/12)*360 + (1/2)*220 + (5/8)*400
