[Siafu na Manga]

let the whole class equals to M
and total number of boys equals to Y,
also total number of female equal to X

na hapo ushaambiwa kuwa 75% ya darasa zima ni boys
that means 25% ni female


vile vile umeambiwa kuwa 135 ya female wamefeli ambao ni sawa na 54% ya female wote

kwa hiyo sasa fanya hivi.

54% of X=135
0.54X=135
X=250
kumbe idadi ya female wote ni 250.

papo hapo kumbukua kuwa 25% of the whole class ni female hivyo...

25% of Z= X
0.25Z=X=250
0.25Z=250

Z=1000. ambao ndo idadi ya darasa zima.   ..

hapo kwa haraka haraka utagundua kuwa total number ya boys ni 750.

kwa hiyo idadi ya
boys walio pass exam

70% of 750 == 525

and idadi ya female walio pass exam

46% of 250== 115..



kwa haraka haraka nikiwa kwenye bodaboda akili yangu imeniambia hivi

Siyo sets hiyo mkuu, ni percentages.
Ulivyoona male and female, pass and failed ukajua sets!

Kwa hiyo jibu lako ni lipi hapo mkuu?
Swali linasema "How many female and male candidates passed?"

 

[Kibishi]

Hizi gesabu ndio zilikatishaga tamaa ya kusoma engineering.

Hesabu ilikukatishaga tamaa form ngapi?
Mimi hesabu zilizonikatishaga tamaa ni zile za "How many liters of %x milk solution should be added to liters of %y acid solution to make a solution of?"

Kwa hiyo jibu lako ni lipi hapo mkuu?
Swali linasema "How many female and male candidates passed?"

male hapo ni hao 525 and female ni 115

 

[Kibishi]

male hapo ni hao 525 and female ni 115

Njia yako ni sahihi, ila hujamalizia kujibu.
Swali linamaanisha "watahiniwa wangapi 'JUMLA' walifaulu?"

Since 135 is the number of female candidates failed, and it is equal to 54%, the total percentage of females = 100% = 1,
Number of girls passed = 100% - 54% = 46% = 0.46 (in decimal) thus,
135 = 0.54
? = 0.46
On cross multiplying
(0.46 x 135) ÷ 0.54
= 115 females.
Thus 115 females passed.
The percent of total girls = 100% - 75% = 25%
= 0.25
0.25 = (115 + 135)

0.25 = 250
0.75 = ?
By cross multiplying,
(0.75 x 250) ÷ 0.25 = 750 total male candidates.
Taking 70% x 750 =
525.Thus, 525 male candidates passed.

Out of the candidates who sat for a qualifying test at CBE in a certain year, 75% were males. 54% of the female candidates failed and 70% of the male candidates passed. If 135 female candidates failed, how many female and male candidates passed?
N.B:
Usibandike jibu peke yake, onyesha na njia. Ukiweka jibu peke yake nitakuchunia.

Soln:
Let
A = Males who sat for the test
B = Females who sat for the test

Given: 54% of B failed the test, and their number is 135.
ie 54%*B = 135

54B/100 = 135, B = 135 * 100/54

B = 250.

Therefore: Female candidates who passed is 250-135=115.

Note: A is 75% of total candidates, thus gives B a 25%.
25% of (A+B)= 250, then A+B = 250*100/25 = 1000.

A= 1000-B (remember, B = 250).

Then, A = 750.

70% of Male candidates passed, ie 70%*750 = 525

Therefore: Male candidates who passed is 525.

Malizia sasa.

Mkuu, swali lhalimaanishi hivyo, linamaanisha idadi ya wakike waliofaulu ni wangapi na wale Wa kiume waliofaulu ni wangapi, lingeuliza "how many candidates passed ?" Ndo tungejumlisha hiyo idadi na kupata 640 candidates.Kama jibu wameandika kwamba ni 640 candidates WAMEINGIA CHAKA !

swali limesema ni female wangapi na male wangapi walifaulu mtihani.
kwa hiyo hapo lazima uonyeshe kwa idadi yao tofauti tofauti

halikutaka how many candidates passed the exams
