Answer:
1.
Say Parmit has x marbles then
According to the condition,
5x+7=37
5x=30
x=6.
Hence, Parmit has 6 marbles.
2.
Let, Laxmi's age be x years
∴ Laxmi's father's age =4+3x
A.T.Q,
49=4+3x
⟹3x=49−4
⟹x=45/3
⟹x=15
∴ Laxmi is 15 years old.
3.
Let, fruit tree = x
Non-fruit tree = y = 77
from question
y= 2+3x= 77
3x= 77−2
x= 75/3
x= 25 trees
∴ the number of fruit trees is 25
