80 volunteers take a lie detector test to help police see how accurate this test is. If you pass the test, it means the test thinks you are telling the truth all the time.
Of the volunteers, only 54 people will tell the truth at all times and the rest lie on purpose.
The results show that 4 people who are supposed to lie pass the test and 7 people who are telling the truth fail the test.
What was the accuracy of the test?​

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
