Reliance Jio Profit & loss Quiz 1

Correct Option: Rs. 900
Let the original price be x.
Since, at a discount of 30% the article cost Rs. 630.
Then, 630= \frac{70}{100}\times X
X = \frac{630 \times 100}{70}
Original price = Rs 900.

Correct answer: is 565
SP = ( 100 + Profit% /100 ) × CP
= 100 + \frac{13}{100} \times500
= \frac{113}{100}\times 500
= Rs. 565

Correct Option: 9.2
To solve this question, we have to apply the net% effect formula
That is,
X+Y+\frac{XY}{100}
Where X= 40% and y= -22%
By the net% effect formula, we get
Profit % = 40-22-(40\times \frac{22}{100})%
= 18%-8.8%
= 9.2%

Correct Option: 6%
Total selling price of two phones = 9900 + 9900 = 19800
Cost price of first bullock = 18%-8.8% = Rs.9000
According to the question, there is no profit or loss.
Cost price of second bullock = 19800 – 9000 = Rs. 10,800
The selling price of second bullock = Rs. 9000
∴ Loss = 10800 – 9000 = Rs. 1800
∴ Percentage loss on second bullock = 18%-8.8% = 6%

Correct Option: 22.52%
Let the first discount be x%.

Then, 88%\times (100-x)%\times 220 = 150

\frac{88}{100}\times \frac{100-x}{100}\times 220 = 150

8800 – 88x = 6818.18

88x = 1981.81
x = 22.52%

Correct Option: 12000
Let the cost price of the television set be ₹ x

Then,
(100 + 12)% = 14400

100% = x

By the cross multiplication, we get

x = \frac{14400\times 100}{112}

= Rs. 12000

Answer: Option 77.7%
CP/SP = 9/11
Let,
CP= 9x
SP= 11x
When the MRP is 100% more than CP so,
MRP= 18x
Discount%= \frac{18x-11x}{9x}\times 100= 77.7%

Correct Option: 75% gain
Total CP = \left ( 90%\times 80%\times 35000 \right )+2000

= ₹ \left ( \frac{90}{100}\times \frac{80}{100}\times 35000 \right )+2000

= ₹ (18000 + 2000) = ₹ 20000

∴ CP = ₹ 20000, SP = ₹ 35000

Gain = ₹(35000 – 20000) = 15000
Gain% = \frac{15000}{20000}\times 100 %
= 75%

Correct Option: RS 500
Let Vivek purchase the watch for ₹ x.

Then, according to the question,

130% of 90% of x = 585

⇒ \frac{130}{100\times }\frac{90}{100}\times x = 585

⇒ x = 117x = 58500 ⇒ x = ₹ 500

Correct Option: 660.63
Cost price = Rs. 540 Rs.

Profit = 540 × 15% = 81

S. P. = 540 + 81 = 621

Discount % = 6%

Discount is always given on the marked price, So
Let the marked price be X
x × 94% = 660.63

x = 660.63 Rs.
