Answer : B
Explanation
Let the required distance be x km. then, x/ (5/2) - x/ (7/2) = 12/60 ( ∵difference between two times is 12 min.) ⇒ 2x/5 - 2x/7 = 1/5 ⇒ 14 x-10 x = 7 ⇒ 4x= 7 ⇒ x= 7/4 Required distance = 7/4 km

Answer : D
Explanation
Let us consider all the six books are bought at least cost 150 x 6 = 900 Selling at the highest price 325 x 6 = 1950 ∴ Profit = selling price ? cost price =1950 - 900 = 1050
Q 4 - The L.C.M of two numbers is 12 times their H.C.F and sum of H.C.F and L.C.M is 403. Having one number as 93, find the other one.
Answer : B
Explanation
Let L.C.M =x and H.C.F = y . Then, X= 12y and x+y = 403 ⇒12y+y = 403 ⇒13y= 403 ⇒y = 403/13 = 31 ∴ x= (12*31 ) = 372 Let the other number be z. then, 372*31 = 93*z ⇒ z = (372*31)/93 =124 Hence , the other number is 124 .
Q 5 - The average age of 8 men is increased by 2 years when two of them whose ages are 21years and 23 years are replaced by two new men. The average age of the two new men is?
Answer - C
Explanation
Total age increased = (8 x 2) years = 16 years. Sum of ages of two new men = (21 + 23 + 16) years = 60 years Therefore age of two new men = 60⁄2 = 30 years.

Payment to be made = P.W. of Rs. 10028 due 9 months hence = Rs ((100*10028))/(100+(12*3/4) )= Rs ((100*10028))/109= Rs 9200
Q 8 - A man on the top of a vertical observation tower observes a car moving at a uniform speed coming directly towards it. If it takes 10 minutes for the angle of depression to change from 45° to 60°, how soon after this will the car reach the observation tower?
Answer : B
Explanation
Let AB be the tower and C and D be the two positions of the car. Then,from figure AB/AC=tan 60 =√3 => AB=√3AC AB/AD=tan 45=1 => AB=AD AB=AC+CD CD=AB-AC=√3AC - AC=AC (√3-1) CD = AC (√3-1) =>10 min AC=> ? AC/(AC(√3-1)) x 10=?=10/(√3-1)=13.66=13 min 20 sec(approx)
Q 9 - If the the total investment of a business is an amount of rs. 5000. Ajay invested 4000 Rs. more in the comparision of Bijender and Bijender invested 5000 more in the comparision of Chman . At the end of the year, Rs. 35000 earned in the form of profit then what should be the share of Ajay?
Answer : A
Explanation
If we can assume that the C , B and A have the investment of Rs. x , (x+5000) and Rs. (x+9000) respectively. Then, X+(x+5000)+(x+9000) =50000 ⇒ 3x = 36000 ⇒ x =12000. C =Rs. 12000 , B = Rs. 17000 and C = Rs. 21000 A : B : C = 21000 : 17000: 12000 = 21: 17: 12 Share of A = Rs. (35000* 21/50) = Rs. 14700
