3-topshiriq. Mahsulot hajmi o’zgarishiga ishchilar soni, o’rtacha ishlangan kun hamda bir kunga to’g’ri keladigan mahsulot hajmining ta’sirini tahlil qiling

Ko’rsatkichlar(ming so’m)	O’tgan yil	Haqiqatda	Farqi (+;-)
Ishchilar soni, kishi (X)	150	200
Bir ishchiga to’g’ri keladigan o’rtacha ishlangan kun, kishi kuni (U)	255	240
O’rtacha ishlangan bir kunga to’g’ri keladigan mahsulot hajmi, ming so’m (Z)	1200	1500
Mahsulot hajmi, ming so’m (F)

U=x*y (U- natija, x – birinchi omil, y – ikkinchi omil)	∆Ux = x1*y0 – x0*y0 ∆Uy = x1*y1 – x1*y0 Tekshirish: ∆U = ∆Ux + ∆Uy 1- hisobot davri, 0 –o’tgan yoki reja davri
U=x*y*z	∆Ux = x1*y0*z0 – x0*y0*z0 ∆Uy = x1* y1*z0 – x1*y0*z0 ∆Uz = x1*y1*z1 – x1*y1*z0 TEKSHIRISH: ∆U = ∆Ux + ∆Uy + ∆Uz
4 OMILLI U=x*y*z*q	∆Ux = x1*y0*z0*q0 – x0*y0*z0*q0 ∆Uy = x1*y1*z0*q0 – x1*y0*z0*q0 ∆Uz = x1*y1*z1*q0 – x1*y1*z0*q0 ∆Uq = x1*y1*z1*q1 – x1*y1*z1*q0
∆U = ∆Ux + ∆Uy + ∆Uz + ∆Uq
U=x / y	∆Ux = x1 / y0 – x0 / y0 ∆Uy = x1 / y1 – x1 / y0
∆U = ∆Ux + ∆Uy
