In a certain university admissions department, 70 more males than females submitted applications for admissions. 20% of the fema
Anuta_ua [19.1K]

Answer:

In total, 1130 people applied in the University.

Step-by-step explanation:

Total applicants admitted = 256

Let the number of females  who applied in University =   k

So, the number of males who applied =  ( k + 70)

Now, 20 %of females are admitted ⇒ 20% of (k) is admitted

or, the number of females admitted in university =  \frac{20}{100}  \times k = 0.2k

Also , 25 %of males are admitted ⇒  25% of (k + 70) is admitted

or, the number of males admitted in university =  \frac{25}{100}  \times (k+70) = 0.25(k+70)

So, according to the question:

0.20k + 0.25(k+70) = Total admissions = 256

or, 0.2k + 0.25k + 17.5  = 256

⇒0.45k = 238.5

or, k = 238.5/0.45 = 530

Hence, total number of females who applied = 530

And Total males who applies = ( k + 70) = 600

Now,  TOTAL Applications = MALE applications + FEMALE applications

                                              = 530 + 600 = 1130

Hence, in total 1130 people applied in the University.
