Jai Narayan sells two radio sets for 2288 each.
tester [12383]

Answer:

1%

Step-by-step explanation:

The selling price for each radio is $2288.

Total selling price is 2\times 2288=$4576.

Profit is 10%.

Loss is also 10%.

Cost price=\frac{S.P\times 100}{100+gain(in\;percent)}

Cost price=\frac{S.P\times 100}{100-loss(in\;percent)}

Utilizing the formula,

Cost price of the first radio is \frac{2288\times 100}{110}=$2080.

Cost price of the second radio is \frac{2288\times 100}{100-10}=$2542.2.

The combined cost price for both radios totals 2080+2542.2=$4622.2.

Total cost price exceeds total selling price.

Loss equals selling price minus cost price.

Loss is calculated as 4622.2-4576=$46.2.

Loss%=\frac{Loss}{C.P}\times 100

Loss percentage is \frac{46.2}{4622.2}\times 100=1%.

Thus, the loss is 1%.

The sum of four consecutive odd numbers is 368 find the numbers​
lawyer [12517]

Answer:

The four odd numbers in sequence are 89, 90, 91, and 93.

Step-by-step explanation:

Designate the four consecutive numbers as x, x+2, x+4, and x+6.

Based on the information given in the question

x + (x + 2) + (x + 4) + (x + 6) = 368

4x + 12 = 368

4x = 356

x = 89

Consequently, the numbers are 89, 90, 91, and 93.

Hope this is helpful:)
