agamevu: come on bro, you want me to do all your homework too?! if 1/8 of total income is 2400, then its obvious that 2400x8 would be the total income |

Kylekent59:Let total income be T 1/8 of Total income (T)=amount spent on present 1/8 xT=2400 T/8=2400 T=8×2400 T=19200 Thus total income is #19200 Amount he spent on food =food fraction x T Food fraction =1-½-⅛=½-⅛=⅜ Amount spent on food=⅜x19200=#7200. Thanks for the mention sir. |

agamevu: After spending on cloth,for the remainder: 1 - 1/2 = 1/2 ( remainder after taking out cloth) After spending on X-mas present, remainder is: 1/2 - 1/8 = 3/8 ( remainder after taking out x-mas presnt) Therefore, 3/8 is left for Food. His total income? But on X-mas prst he spent 2,400 Hence to get the total 1/8 of X( total income) = 2,400 (amt spent on x-mas prst) 1/8 x X = 2,400 X = 2,400 x 8 = 19,200 His total income is #19,200. The amount he spent on food? The fraction on food is 3/8 ( after taking out cloth and x-mas prst) then 3/8 of the total income = amt spent on food 3/8 x 19,200 = 7,200 He spent #7,200 on food |

Hmmm |
Re: Please Help Me Solve This Mathematics Question by dejt4u(m): 2:02pm On Dec 30, 2019 |
Mrshape:I have different answer.. Total income is N38,400 and N16,800 was spent on food |
Re: Please Help Me Solve This Mathematics Question by dejt4u(m): 2:05pm On Dec 30, 2019 |
Mrshape:I don't want to agree with this.. Read the question again.. 1/2 of his income was spent on clothing for the family, THEN 1/8 on presents at xmas and the rest on food. |
Re: Please Help Me Solve This Mathematics Question by dejt4u(m): 2:11pm On Dec 30, 2019 |
dejt4u:If the total income is represented as x, Then for presents at Xmas, ⅛ of (x-½x) = 2400, ⅛ × x/2 = 2400, x/16 = 2400, x = N38,400 |
Re: Please Help Me Solve This Mathematics Question by peppo4live: 3:36pm On Dec 30, 2019 |
Solution Clothing = 1/2 Xmas. =1/8 Total spending on clothing and Xmas =1/2+1/8 =5/8 Total income in fraction = 8/8 Therefore, the rest on food = 8/8 - 5/8 = 3/8 Total income if he spends N2400 on Xmas 1/8 X Total income = N2400 T/8 = N2400 Making T the subject T= N19200 On food 3/8 X N19200 = N7200 Total income = N19,200 What he spent on food = N7,200 |

Mrshape:I love equations |
Re: Please Help Me Solve This Mathematics Question by Mrshape: 5:02pm On Dec 30, 2019 |
dejt4u:It says 1/8 of the income is spent on present That sentence is a continuation of the previous phrase So no need to be writing of income every where sir Simple say 1/8 on present. Clear sir? |
