well it can be easily solved using 10th class identity
but i can remember it is a ncert question of class 8 or 9
so
(30-20)x7=70+30=100
so it will take 7+1=8mins
but i can remember it is a ncert question of class 8 or 9
so
(30-20)x7=70+30=100
so it will take 7+1=8mins
similarly for 7 mins he does so...class 2
hmm
so after 7mins he had climbed 70m
7 comes from where
ok ok ab smjh aagya
then in 8th min 70+30=100 so in 8th minute he reaches at the top hence his goal accomplished so total time taken is 8mins
