hey mate

here is your answer

the frog climbs 1 m in 2 second.

thus ,it climbs 7 m in 14 second

and therefore ,it makes the 8th jump and reaches 10m

thus,it climbs in 8 jumps

Answer 2

The frog will reach the roof after 8 jumps.

Explanantion:

The roof is connected with the pole of 10 M height.

The frog jumps 3 metres and then slips 2 metres.

So in first jump, it covers 1 meter.

In second jump, it will touch 4 meters and fell two meters, covering 2 meters.

So every 1 jump, it will cover additional distance of 1 meter.

Hence, it will climb 7 m after 7th jump.

On 8th jump, it will cover 10 meters (7 meters+3 meters) & will reach the roof.

Thus, the frog will reach the roof after 8 jumps.
