Step-by-step explanation:
let the number of cookies sold on first week be=x
let the number of cookies sold on second week be= x+4
let the number of cookies sold on third week be= (x+4)×2
total number of cookies sold = 351
now 351=(x)+(x+4)+(x+4)×2
351=3x+(4+4×2)
351=3x+12
3x=351-12
3x=339
x=339÷3
x=11
Cookies sold on first week=113
Cookies sold on second week= 113+4= 117
Cookies sold on third week =113+4×2 = 113+8=121
now add all the number of cookies solved for confirmation
=113+ 117+ 121= 351
Answer:
thus the father is 64 years and son is 37years
Step-by-step explanation:
Let father be X and son be y
X=27+Y...........(I)
X-10=2(Y-10)
putting the value of X from eqn(I)
27+Y-10=2Y-20
Y+17=2Y-20
17+20=2Y-Y
37=y
X=27+Y
X=64
