Question : To cover a certain distance at a speed of 60 km/hr, a train takes 15 hours. If it covers the same distance in 12 hours, what will its speed be?
Option 1: 65 km/hr
Option 2: 70 km/hr
Option 3: 75 km/hr
Option 4: 80 km/hr
Correct Answer: 75 km/hr
Solution : Given: A train takes 15 hours to cover a certain distance at a speed of 60 km/hr. Distance = Speed × Time = 15 × 60 = 900 km $\therefore$ Required speed to cover this distance in 12 hours = $\frac{900}{12}$ = 75 km/hr

Question : For what value of m will the system of equations 18x – 72y + 13 = 0 and 7x – my – 17 = 0 have no solution?
Option 1: 28
Option 2: 24
Option 3: 9
Option 4: 12
Correct Answer: 28
Solution : To have no solution, the two equations should represent parallel lines. For a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, to be parallel lines $\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq\frac{c_1}{c_2}$ this formula must
Question : Select the most appropriate option that can substitute the underlined segment in the given sentence.
Either you and he will have to pay for this damage.
Option 1: or he
Option 2: with he
Option 3: but he

Option 4: 8
Correct Answer: 24
Solution : Given: A and B can do a piece of work in 15 days. B and C can do similar work in 12 days and C and A in 10 days. (A+B) in 1 day can do $\frac{1}{15}$ part of the work. (B+C) in 1 day
