120÷5=24

24+40=64

5:3

5+3=8

(5/8)×64=24

Jai Narayan sells two radio sets for 2288 each.

san4es73 [151]

Answer:

1%

Step-by-step explanation:

S.P of each radio=$ 2288

Total S.P= $2\times 2288=$ $4576

Gain=10%

Lose=10%

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

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

By using the formula

C.P of one radio= $\frac{2288\times 100}{110}=$ $2080

C.P of another radio= $\frac{2288\times 100}{100-10}$ =$2542.2

Total C.P of two radios=2080+2542.2=$4622.2

Total C.P >Total S.P

Loss=S.P-C.P

Loss=4622.2-4576=$46.2

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

Loss %= $\frac{46.2}{4622.2}\times 100=$ 1%

Hence, his loss 1%

iren [92.7K]

Answer:

30

Step-by-step explanation:

Equation y = 3x + 210

if y = 10x

10x = 3x + 210

or, 10x - 3x = 3x + 210 - 3x

or, 7x = 210

or, x = 210 ÷ 7

or, x = 30
