- 4
b=3c
b-1=52+2(c-1)
b=2c+51
c=51
b=3*51=153
c+b=51+153=204 - 11 years agoHelpfull: Yes(9) No(1)
- (2).202
last yr age of the banyan tree is ,b=2c+52
the next year it is 3 times of coconut tree ie,b=3c or b=2c+53
equating 3c = 2c+53
so age of coconut tree is c= 53
thrfre sum of the ages of both the trees s 4c ie 202
option(2) - 11 years agoHelpfull: Yes(1) No(4)
- 3x,x are the ages of banyan and coconut trees respectively.
last year ages of trees is 3x-1 and x-1
s0 that 3x-1=52+2(x-1)
solve the above equation we get x=51
sum of the ages=x+3x=4(51)=204 - 11 years agoHelpfull: Yes(1) No(0)
