Question

a monkey is trying to climb a coconut tree. he takes 3 steps forward and slips back 2 steps downwards. each step is 30 cm and each backward step is 40cm. how many steps are required to climb a 100cm tree? Thank you!

Answer 1

50

3x30=90
2x40=80
so
90cm up
80cm back
10cm gain
5 steps per gain
10 gains to gain 100cm
5 steps x 10 gains = 50 steps
