Answer

Correct Option is Rs.648000

Solution:Let cost price of all mouse with kunal and Mohan in 2020 be Rs. ’x’.
And cost price of all mouse with Tashu & Sonam in 2020 and all mouse with Kunal in 2021 =Rs ’y’.
Cost price all mouse with Tashu in 2021= Rs. 400
Cost price of shirt with Tashu in 2020 & cost price of shirt with Mohan in 2020 be 3z & 2z respectively.
Cost price of all mouse with Mohan in 2021 = 400-150=Rs. 250
The sum of cost price of all the mouse with kunal in both years and cost price of mouse with Mohan in 2020 is 1200
So, y+400+x=1200
x+y=800…..(a)
And y-x=x-250
2x-y=250 ….(b)
From (a) & (b)
x = Rs. 350 and y = Rs.450
Cost price of shirt with Sonam in 2020 = 3/5×600=Rs.360
Cost price of shirt with kunal in 2020 = 40/100×450=Rs. 180
In 2020 sum of the cost price of all the shirt with four sellers was Rs. 200 more than cost price of Iron with Mohan in 2020
So, 3z+180+2z+360=2600
5x=2050
x=412
Cost price of shirt with Tashu in 2020 = 3×412=Rs.1236
Cost price of shirt with Mohan in 2020 = 2×412=Rs.824
