Answer:

Question 9 answer

Explanation:

The principal amount at which the consignment has purchased will be Rs. 1,50,000

Explanation:

We know that the formula for  

Simple Interest

Where P is principal amount, T is the time in years, R is rate at which the transaction is done.

In this problem, T is not mentioned, we can neglect it, first case is the profit and second one is the loss.

2/3 of the consignment is sold in profit

If x is the principal amount, then (2/3) x will be the amount under first transaction, rate will be 105/100 as it provides 5% profit.

Therefore, let us calculate the amount say in the first transaction.

Let be the second transaction, amount will be x/3, rate will be 98/100 as here the loss rate is 2%.

Principal Amount = Total transaction amount – Profit

Given total profit after transactions = 4000

Hence, the principal amount = Rs 1,50,000

Ans 10.)

Net worth of total sugar =

rs 4500

1/3 of total sugar =1/3*4500=1500

10% of 1500=150

so,he get rs 1500+150=1650 when he sold 1/3 of total sugar at 10% profit.

He must gain 12% profit on total sugar

so, total sugar sold at rs4500+540= rs 5040

he had already gained rs 1650

so, now he want rs 5040-1650=rs 3390

he had left with sugar worth rs 4500-1500=3000

Now, let the gain percent on 2/3 of sugar be x

so, x% of 3000 = 3390-3000

x/100*3000= 390

x*30=390

x= 390/30

x= 13

Therefore,he must sold the remaining sugar at 13% gain so as to get 12% gain on total sugar
