Question

Alisha has Rs. 4900 with her and spends 36% of it on groceries. How much money is left with her?
(a) Rs. 1764
(b) Rs. 3136
(c) Rs. 3276
(d) Rs. 3336

Answer 1

Hint: First, we will find a discount on Rs. 4900 which is given as $discount=amount\times discount\%$ . After finding this, we will subtract this amount from the total given amount. That answer will be the final amount left with Alisha after spending 36% on groceries.

Complete step-by-step answer:
Here, it is given that 36% of Rs. 4900 has been used on groceries, so we will first find how much is 36% of 4900 using the formula $discount=amount\times discount\%$ . Using this, we can write it as
$=4900\times 36\%$
On further solving, we get as
$=4900\times \dfrac{36}{100}$
$=49\times 36$
$=1764$
So, 36% of Rs. 4900 is Rs. 1764. So, Alisha has spent Rs. 1764 on groceries.
Now, to find how much is left with Alisha we have to subtract amount of 36% i.e. Rs. 1764 from total amount i.e. Rs. 4900.
On subtracting, we get
$=4900-1764=Rs.3136$
Thus, Rs. 3136 is left with Alisha.
Hence, option (b) is correct.

Note: Sometimes students forget to subtract discounted price from original price i.e. after finding discounted price which is Rs. 1764, students directly write this as an answer which is wrong. We have to subtract this and then that answer will be the correct answer. So, do not make this mistake.
