(MATHS QUIZ) Percentages word problems.

[Ziege]

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

M=Z?
