3A = 5B = K

∴ A = k/3, B=k/5

∴ (A+B) / B = 8/3

Sum of first 29 even numbers = (2 + 4 + 6 + … + 58)

=2 × (1 + 2 + 3 + … + 29) 5 consecutive odd numbers are-

23, 25, 27, 29, 31

∴ Product of First and last number

= 23 × 31

=713

No. of Pens, he sell for a rupee to

Gain 50% = 9/150×100

= 6 pens ∴ Profit % on S.P = (310 – 140) / 310 × 100

=170 / 310 × 100

55% ∴ % decrease in consumption

= ((100 –  80)) / 100 × 100 = 20%

25% →  6

150% → 6 / 25 × 150 =36

Let the speed of Boat = B km/hr

And the speed of stream = S km/hr ∴ By solving. B = 24, S = 16

∴ Speed of the stream = 16 km/hr.

Let the distance b/w two consecutive trees = 1m ∴ 21 → 18 sec.

(12 + 21 + 16) = 49m  → 18/21 × 49

= 42 sec.
