Q 1 - Two train approach one another at 30 km/hr and 27 km/hr from two spot 342 km separated. After how long will they meet?
Answer : B
Explanation
Suppose the two trains meet after x hours. Then, 30x+27 x= 342 ⇒ 57 x = 342 ⇒ x = 342/57 = 6. So the two trains will meet after 6 hours.
Q 2 - If 5 men or 9 ladies can complete a bit of work in 19 days, 3 men and 6 ladies will do likewise work in
Answer : D
Explanation
5 men 1 day work = 1/19 ⇒ 1 man's 1 day work = 1/95 9 women 1 day work = 1/19 ⇒1 women 1 day work = 1/171 (3 men + 6 women) 1 day work = (3/95 + 6/171) = (27+30)/855 = 57/ 855 = 1/15 ∴ 3 men and 6 women can finish the work in 15 days.
Answer : C
Explanation
given exp. = (3/2) / 1+ 1(/5/4) = (3/2)/ (1+4/5) = (3/2) /(9/5) = ( 3/2 * 5/9) = 5/6
Q 4 - Sum of two numbers is 60 and their H.C.F and L.C.M are 12 and 72 respectively. One of the numbers is:
Answer : B
Explanation
Let the numbers be 12 a and 12 b, where a and b are co primes. Then, 12 a *12 b = 12 *72 ⇒ ab= 6 co-primes with product 6 are a = 2, b= 3 ∴ numbers are (12*2, 12*3 ) i.e 24 and 36
Q 5 - 12 + 22 ... + x2 = [x(x+1)(2x+1)]/6. What is 12 + 32 +... + 202?
Answer : A
Explanation
(12 + 32 ... + 202) = (12 + 22 ... + 202) - (22 + 42 ... + 192) Using formula (12 + 32 ... + n2) = [n(n+1)(2n+1)]/6 [20(20+1)(40+1)]/6 - (1 x 22 + 22 x 22 + 22 x 32 + ... + 22 x 92 + 22 x 102) = 2870 - 22(12 + 22 + ... + 192) = 2870 - 4(1 x 2 x 39)/6 = 2870 - 52 = 2818
Q 6 - The average age of five officers in a department is 32 years. If the age of their supervisor is added the average increases by 1. What is the supervisor's age?
Answer : C
Explanation
Supervisor?s age = 32 + 6 = 38 years
Q 7 - If the true discount on sum due 3 years hence at 10% per annum be Rs. 180, the sum due is
Answer : A
Explanation
Present worth=( 100*TD)/R*T=( 100 *180 )/10*3=Rs.600.
Q 8 - The two hands of a clock will be together between h and (h+1) o'clock at
A - (60/11)h minutes past h o' clock
B - (50/11)h minutes past h o' clock
Answer : A
Explanation
At h o' clock, the minutes hand is 5 h minute spaces behind the hour hand. The minute hand gains 55 min spaces in 60 mins. ∴ The minute hand will gain 5h minute spaces in 60/55 * 5h = 60h/11 minutes. ∴ The two hands will be together between 'h' and 'h+1' o' clock at (60/11)h minutes h o' clock.
Q 9 - Ajay , Bijender and chaman started a business and invested Rs. 20000 each partner .After the period of 4 month, some changes are made in investment just like Ajay withdraw Rs. 5000, Bijender and chaman both add 6000 each in the invested capital. An amount of Rs. 69900 recorded as a profit in the firm. What should be the share of Bijender in profit?
Answer : B
Explanation
Ajay : Bijender: chaman = (20000*5+15000*7) : (20000*5+ 16000*7) :(20000*5+26000*7) = 205000: 212000 : 262000 = 205 : 212: 282 Share of B in profit = Rs. (69900* 212/699) = Rs. 21200
Q 10 - The aggregate surface territory of a strong barrel is 231 cm2. On the off chance that its bended surface zone is two ?third of its aggregate surface zone, then its Volume is:
Answer : A
Explanation
(2πrh+2πr2) =231 and 2πrh= 2/3*231= 154 ∴154+ 2πr2 =231 ⇒2*22/7*r2= (231-154) =77 ⇒r2 = (77*7/44)= 49/4 ⇒ r =7/2 cm ∴2*22/7*7/2*h= 154 ⇒ h= 7cm ∴ Volume = πr2h = (22/7 *7/2 * 7/2 * 7) cm3 = 539/2 =269.5 cm3
