A VCR and TV were bought for 78.000 each. The shopkeeper made

Zielflug [23.3K]

Answer:

Profit % is 1.94% .

Step-by-step explanation:

The CP of both VCR and TV were same that is Rs 78,000 . So ,

$=> CP \ of \ the \ buyer \ = \ Rs78,000 \times 2 = Rs 156,000$

As per Question , on one he made a loss of 4% and profit of 8% on the other .

And , the net SP would be ,

$=> Total \ SP \ = \ \dfrac{96}{100}\times Rs 78,000 + \dfrac{108}{100}\times Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}$

So , here clearly SP > CP . So , there's a profit .Hence profit % would be :-

$=> Profit \% = \dfrac{ SP - CP }{CP}\times 100 \\\\=> Profit \% = \dfrac{Rs 159,040-Rs156,000}{Rs156,000}\times 100 \\\\=> Profit\% = \dfrac{3040}{156000}\times 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}$

A company makes two calculator models, one designed specifically for financial use and the other designed for scientific use. Th

mihalych1998 [28]

Answer:

280 financial
20 scientific

Step-by-step explanation:

The linear programming problem can be formulated as ...

minimize 10f +12s subject to ...

10f +20s ≥ 3200 . . . . number of chips used

f + s ≥ 300 . . . . . . . . . .number of switches used

f ≥ 100 . . . . . . . . . . . . .minimum number of financial calculators

Graphing these inequalities, we find the feasible region to be bounded by the points (f, s) = (100, 200), (280, 20), (320, 0). The one of these that minimizes the number of production steps is ...

f = 280, s = 20

280 financial and 20 scientific calculators should be produced to minimize the number of production steps.
