Answer 2

Answer:

Steps:

(a) Number of marbles Parmit has 3737. Let the number of marbles Parmit has be xx. According to question,

5x+7=375x=30x=305=65x+7=375x=30x=305=6

Therefore, Parmit has 77 marbles

(b) Let the age of Laxmi be xx. Age of Laxmi’s father be 4949 years

According to question,

3x+4=493x=49–4=45x=453=153x+4=493x=49–4=45x=453=15

Therefore, Laxmi’s age is 1515 years

(c) Let the number of fruit tress be xx. Then the number of non-fruit trees are 3x+23x+2

According to question,

3x+2=773x=77−2=75x=753=253x+2=773x=77−2=75x=753=25

The number of fruit trees planted are 2525.
