Answer 1

hey mate!!

here is ur answer

_____________________

$the \: price \: of \: scooter \: last \: year \: = 34000$

$percentage \: increase = 20\%$

$increase \: in \: money \: = 34000 \times \frac{20}{100} = 6800$

$the \: price \: now = 34000 + 6800 = 40800$

Sunitha used unitary method and said that 20% increase means 100 increased of 120

then the money next year will be

34000×120/100=40800

hope the answer helps u

Answer 2

Answer=32300

Method -1

Consider Amit used the first method

Amit said that he would first find the increase in the price, which 20% of ₹34,000,and then find the new price.

$20\% \: of \: rupees \: 34000 = \frac{20}{100} \times 34000 \\ rupees \: 6800$

New pice=old price + increase

$= 34000 + 6800 \\ = 40800$

Method -2

Sunita used the second method (unitary method) Sunita used unitary method and said that 20% increase means,

$100..increased \: of \: 120$

So, ₹34,000 will increase

$increased \: price \: = \frac{120}{100} \times 34000 \\ = 40800$

Hence proved in both methods Amit and Sunita used two different method

Extra Explanation to make deep the answer

Similarly, a percentage decrease in price would in price would imply finding the actual decrease followed by the from the original price.

Suppose in order to increase it's sale, the price of scooter was decresed by 5%.

Than we should find the properties of scooter.

price of scooter =₹34,000

Reduction=5% of ₹34,000

=₹5/100×34,000=₹1,700

New price =old price - deduction

=₹3,400-₹1,700=₹32,300
