Question

Hello.............


GM mates

Answer 1

Answer:

let, the mango trees be X.

then, the berry trees is x-40.

therefore, X+x-40 is equal to 100 percent .

2x is equal to 100+40.

2x is equal to 140.

therefore, X is equal to 140 divided by 2.

X is equal to 70 percent.

That means mango trees is 70 percent and berry trees is 70-30

percent which is equal to 30percent.

Answer 2

Just remember this formula for all this type of problems :-

[ R*100/(100±R) ]

(Here R is given % and + & - sign will come according to first more and less given in Question )

so, now ,

black berry trees are 40% less , using this in formula we get,

Ans :- 40*100/60 = 66.67%
