Question 1

Sonning foizini qanday topish kerak?

Accepted Answer

Sonni foizga ko'paytiring va 100 ga bo'ling. Masalan, 50 000 ning 15% i = 50 000 × 15 / 100 = 7 500. Kalkulyatorda 'Sonning X%' rejimini tanlang.

Question 2

Bir son ikkinchisining necha foizini tashkil qilishini qanday aniqlash kerak?

Accepted Answer

Qismni butuniga bo'ling va 100 ga ko'paytiring. Masalan, 50 000 dan 7 500 = (7 500 / 50 000) × 100 = 15%. 'Butunning qismi' rejimidan foydalaning.

Question 3

Foizga o'zgargandan keyin sonni qanday hisoblash kerak?

Accepted Answer

Yangi qiymat = boshlang'ich × (1 + foiz / 100). 20% ga oshirishda: 50 000 × 1.2 = 60 000. 15% ga kamaytirishda: 50 000 × 0.85 = 42 500. '% ga o'zgartirish' rejimidan foydalaning — kamaytirish uchun manfiy foiz kiriting.

Question 4

Ikki son o'rtasidagi foiz o'zgarishini qanday hisoblash kerak?

Accepted Answer

Foiz o'zgarishi = (yangi − eski) / |eski| × 100. Masalan, 50 000 dan 62 500 gacha = (62 500 − 50 000) / 50 000 × 100 = +25%. '% dagi o'zgarish' rejimidan foydalaning.

Question 5

QQS bilan summadan QQSni qanday ayirish kerak?

Accepted Answer

QQSsiz summa = QQS bilan summa / (1 + stavka/100). 12% QQS uchun: 1.12 ga bo'ling. Masalan, 112 000 / 1.12 = 100 000. Buning uchun Solvixdagi QQS kalkulyatoridan foydalaning.
