2R â†’ 150

1R = 75

OR

Let number of students who passed the exam = x

Now,

150 Ã— 40 = 60x + 20(150 â€“ x)

6000 = 60x + 3000 â€“ 20x

3000 = 40x

x = 75

Let CP = 100x. then SP = 120x

New CP =140x

New SP = 120x â€“ 24Rs

On solving

then, x = 3

CP = 100 Ã— 3 = 300 Rs

CP of Chair = 3x

CP of table = 4x

CP of 5 chairs = 15x

SP of 5 chairs= 28x

Profit percentage = 13x/15x Ã— 100

= 86.66

Area ; 100 â†’ 81

% decrease =19/100 Ã— 100

= 19%

OR

A : B = 3 : 2

Ratio of speed of train to car = 5 : 4

Speed of car = 4x = 4 Ã— 15 = 60 km/hr

Distance covers after repairing = 49 Ã— 7 = 343 km

Time takesÂ  Before reparing to cover twice distance = (343 Ã— 2) / 42

= 49/3 hr

= 16 hr 20 minutes
