Question 1 & 2
Question 1: In an election between two candidates, one got 55% of the total valid votes, 20% of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got, was
a 2700, b 2900, c 3000 ( Assistant Director IB FPSC 2018)
This is simply a percentage calculation problem;
Total votes =7500 (given)
Total invalid votes = 20% of total votes
So Valid votes = 7500-1500=600
First candidate get 55% of total valid votes
Votes by second candidate =Total Valid Votes – Votes by First Candidate =6000-3300=2700
So the option ‘a’ is the answer
(math portion of job test)
Question 2: A man took loan from a bank at the rate of 12% p.a. Simple interest. After 3 years he had to pay Rs. 5400 interest only for the period. The principal amount borrowed by him was?
a 5000,b 15000,c 12000 ( Assistant Director IB FPSC 2018)
This is problem of simple interest.
We are given;
Rate of interest (R) = 12 pa
Term of Loan investment (T) = 3 yrs
Interest incurred (I) = 5400
Amount borrowed or Principal Amount (P)=?
We know the simple interest formula;
Putting given values
So, the principal amount (borrowed amount was Rs 15000
