38. anonymous

he said he is now older than that age of his sister when she was half young as he was let his age was x and his sisters age was x/2 now he is 4 times that age of his sister means $4*x/2$

39. ganeshie8

Nice, lets see if our answers match

40. imqwerty

^new QH

41. anonymous

and in 15 years their combined age will be equal to 100

42. anonymous

he is asking the present age he tells us past and future ages

43. anonymous

told us *

44. anonymous

ganesh ?

45. anonymous

am I right ?

46. ganeshie8

looks okay but i think we should get a system of 3 equations

47. anonymous

yes ! that is

48. anonymous

past, present and future

49. anonymous

so let their age is x and x/2 in 1 year

50. Loser66

Why 3 equations? The question is "how old are WE now?". Is it not that now, We are 70 years-old? It doesn't ask how old am I and how old is my sister now. Am I right or am I crazy??

51. anonymous

and he is 4 times older than the past age of his sister. then his age and his sister's age will be 4*x/2 and x

52. anonymous

Sorry guys my english so bad :(

53. ganeshie8

To me, "We are 70 years old" sounds more like each of them is 70 years

54. Loser66

ok. :)

55. anonymous

it's ok tangun

56. ganeshie8

the question is fine @tanjung i think it as as good as it can be gramatically/mathematically..

57. Miracrown

$$\color{blue}{\text{Originally Posted by}}$$ @tanjung Sorry guys my english so bad :( $$\color{blue}{\text{End of Quote}}$$ is ok me english no so good to we here on os is family we r one but we are many nd we share the same land nd we sing our song

58. anonymous

is there any option @tanjung ?

59. anonymous

lol yea! sing our songs :d

60. anonymous

It is an essay question. I mean sometimes i will confuse to make an equation or more to applying algebra expression in text question

61. ganeshie8

Start by labeling the variables, Say, the present age of you is $$m$$ and your sister's is $$s$$

62. anonymous

you've gotta be kidding me, you all speak persion these days!! what is this: ajeeb har cheez ma

63. Miracrown

I am the only odd one out, I speak Irish and English only.

64. ganeshie8

persian/hindi/urdu/arabic languages are similar i think i can understand urdu/arabic because i speak hindi

65. anonymous

Thanks for clearing that up

66. Miracrown

I love coming on OS cause I get to meet all you sweet people from around the globe :D

67. anonymous

thanks

68. Miracrown

Bless the day I joined OS.

69. anonymous

XD @tanjung Now I think you should know how old are we now.

70. anonymous

all I understand that that if the past ages of boy and his sister consider x and x/2 respectively then their present age is 3x

71. anonymous

so let make equations past ages let at 1 year their ages were x+x/2=3x/2 now after one more year it will be x+1+x+1/2=3x+2/2 and after 15 year their ages are x+15+x+15/2=100 does it make sense?

72. anonymous

u here ?

73. anonymous

Yup... thank you @sohailiftikhar. I just trying to understand what you mean

74. anonymous
