Question

in an examination 65% passed.if the number of failures is 168. What is the number of those who passed?

Answer 1

Answer:

312

Step-by-step explanation:

let total people=x

passed=65%x

so failed=(100-65)%=35%x

failed=168

so 35%x=168

x=168×100÷35

x= 480

passed=65×480÷100

=312

Answer 2

Answer:

312 is the number of those who passed.

Step-by-step explanation:

Let the population be X

passed = 65% x

so failed = (100-65)% = 35%

failed = 168

35% of x = 168

(35/100)X = 168

35X =168×100

X= 168×100/35

X= 24×20

X= 480

passed = 65 × 480÷100

= 312
