Hello Aspirants
We have come up with Sectional Tests for upcoming LIC AAO 2019 Prelim Exam. Practice the questions to ace the exam.
- P and Q together started a business with investment of Rs.580 and Rs.x resp. If the profit share of Q is 75% more than that of P. Find the value of x.
Rs.1525Rs.1440Rs.1330Rs.1015Rs.1210Option D
Let the profit share of P be Rs.y.
Profit share of Q = Rs.1.75y
Ratio of profit share of P and Q = y:1.75y = 4:7
Now,
580/x = 4/7
=>x = Rs.1015 - Pipe A and pipe B can fill a tank together in (60/7) minutes. If pipe A is 33.33% more efficient than pipe B. Find the time taken by pipe A alone to fill the tank.
12 minutes15 minutes10 minutes17 minutes18 minutesOption B
Let the efficiency of pipe B be 3x and pipe A be 4x.
Now,
1/3x+1/4x = 7/60
=>x = 5
Time taken by pipe A alone to fill the tank = 3x = 15 minutes - Arun took a loan of Rs. 1400 with simple interest for as many years as the rate of interest. If he paid Rs.686 as interest at the end of the loan period, what was the rate of interest?
7%8%6%9%5%Option A
Let rate = R% Then, Time, T = R yearsP = Rs.1400
SI = Rs.686
SI= PRT/100
⇒686 = 1400 × R × R/100
⇒686=14 R^2
⇒R=7% - A man sold two books, one at a loss of 10% and other at a gain of 25%. If the cost price of each book is same. Find the overall profit or loss percentage in this transaction.
8.5%6.9%8.1%6.6%7.5%Option E
Let the CP of each book be Rs.x.
SP of both the books together = 0.9x+1.25x = Rs.2.15x
CP of both books together Rs.2x

Thank you for sharing excellent informations. Your website is so cool. I am impressed by the details that you have on this blog. It reveals how nicely you understand this subject. Bookmarked this website page, will come back for more articles. You, my pal, ROCK! I found simply the info I already searched everywhere and just couldn’t come across. What a great website.
Thanks for your post. I’d like to write my opinion that the expense of car insurance varies greatly from one scheme to another, mainly because there are so many different issues which contribute to the overall cost. For example, the make and model of the automobile will have a tremendous bearing on the price tag. A reliable aged family automobile will have an inexpensive premium than the usual flashy expensive car.
