One day Amit works from 08:00 until 17:00.
The time he spends on filing, computing, writing and having lunch is in the ratio.
Filing:Computing:Writing:Lunch=2:5:4:1.

Calculate the time he spends
(i) writing,
(ii) having lunch, giving this answer in minutes.

(b) The amount earned by Amit, Bernard and Chris is in the ratio 2:5:3.
Bernard earns $855 per week. Caluculate how much (i) Amit earns each week (ii) Chris earns each week (c) After 52 weeks Bernard has saved$2964.
What fraction of his earnings has he saved?

(d) Chris saves $3500 this year. This is 40% more than he saved last year. Calculate how much he saved last year. Please answer all these for me I tried alot but I couldn't. :?: #### UxaiR (a) the total time the man took is 9 hours (i) 4/12 x 9 =3 hours (ii)1/12 x 9 =0.75 hours to covert hours into minutes all we need to do is multiply with 60 0.75 x 60 = 45 minutes (b) (i) firstly we would calculate the total money earned by all three of them that we can find by 855 = 5 /10 x (total money) 8550 = 5(total money) total money = 1710$

now amit earns
2/10 x 1710
=342 $(ii)chris earns 3/10 x 1710 =513$

(C)the total money earned by bernard in 52 weeks =
855 $x 52 = 44460$

44460/2964 <---- now you can simplfy this fraction

(d)let last year saving = x
3500 = 40/100 x "X" + " X "
3500 = 40x/100 +x
350000 = 140 x
x = 2500 $if you dont understand anything let me know i would explain #### Rawan Reda (a) the total time the man took is 9 hours (i) 4/12 x 9 =3 hours (ii)1/12 x 9 =0.75 hours to covert hours into minutes all we need to do is multiply with 60 0.75 x 60 = 45 minutes (b) (i) firstly we would calculate the total money earned by all three of them that we can find by 855 = 5 /10 x (total money) 8550 = 5(total money) total money = 1710$

now amit earns
2/10 x 1710
=342 $(ii)chris earns 3/10 x 1710 =513$

(C)the total money earned by bernard in 52 weeks =
855 $x 52 = 44460$

44460/2964 <---- now you can simplfy this fraction <<<< this is wrong ! You must divide 2964 by 44460 in order to get the right answer which is 1/15 .

(d)let last year saving = x
3500 = 40/100 x "X" + " X "
3500 = 40x/100 +x
350000 = 140 x
x = 2500 $if you dont understand anything let me know i would explain #### Nagham Mojaleed (a) the total time the man took is 9 hours (i) 4/12 x 9 =3 hours (ii)1/12 x 9 =0.75 hours to covert hours into minutes all we need to do is multiply with 60 0.75 x 60 = 45 minutes (b) (i) firstly we would calculate the total money earned by all three of them that we can find by 855 = 5 /10 x (total money) 8550 = 5(total money) total money = 1710$

now Amit earns
2/10 x 1710
=342 $(ii)Chris earns 3/10 x 1710 =513$

(c)the total money earned by Bernard in 52 weeks =
855 $x 52 = 44460$

44460/2964 <---- now you can simplify this fraction( This is Wrong!)
Correct: 2964/44460 which is simplified to become 1/15 {As 2964 is a portion out of 44460 and not vice versa.}

(d)let last year saving = x
3500 = 40/100 x "X" + " X "
3500 = 40 x/100 +x
350000 = 140 x
x = 2500 \$
Other way of solving d:
140%=3500
1%=3500/140
100%=3500/140*100=2500

If you don't understand anything let me know i would explain
