A person spent ₹ 273 on buying a total of 50 packets of chips and biscuits. If the cost of each packet of chips is ₹ 6 and that of each biscuit packet is ₹5, then how many more biscuit packets than chips packets did he buy?

Correct option is B

Given:

The total expenditure is ₹273.

The cost of each packet of chips is ₹6.

The cost of each packet of biscuits is ₹5.

The total number of packets bought is 50.

Solution:

Let the number of chips packets be x and the number of biscuit packets be y.

From the given information, we know:

x + y = 50 (Total packets bought).

6x + 5y = 273 (Total expenditure).

Solve the system of equations:

x + y = 50 (Equation 1)

6x + 5y = 273 (Equation 2)

From Equation 1, solve for y:

y = 50 - x

Substitute y = 50 - x into Equation 2:

6x + 5(50 - x) = 273

Simplify and solve for x:

6x + 250 - 5x = 273

x = 273 - 250

x = 23

Now, substitute x = 23 back into Equation 1 to find y:

23 + y = 50

y = 50 - 23

y = 27

The number of biscuit packets is 27, and the number of chips packets is 23.

The difference in the number of packets:

27 - 23 = 4

So, the person bought 4 more biscuit packets than chips packets.
