Explanation

Principal (P) = 65000

Interest Rate (R) = 3% = 0.03

Interest Amount (I) = 68900 - 65000 = 3900 (since the interest amount is the total amount paid minus the principal)

We can use the formula: I = P × R × T

Rearranging the formula to solve for T, we get:

T = I / (P × R)

= 3900 / (65000 × 0.03)

= 3900 / 1950

= 2 years

So, it takes 2 years for the interest to become 68900.

750000*10/100= 7500

Explanation

• Avg of 6 numbers = 30
• Sum of 6 numbers = 6 x 30 = 180
• Avg of first 4 numbers = 25
• Sum of first 4 numbers = 4 x 25 = 100
• Avg of last 3 numbers = 35
• Sum of last 3 numbers = 3 x 35 = 105
• Now, let's find the 4th number:
• Sum of first 3 numbers = Sum of first 4 numbers - 4th number
• = 100 - 4th number
• Sum of first 3 numbers = Sum of all 6 numbers - Sum of last 3 numbers
• = 180 - 105
• = 75
• So, 75 = 100 - 4th number
• 4th number = 100 - 75
• = 25

Explanation

Let the original cost of the TV = C

Cost of TV with 10% GST = $\frac{110}{100}$C

Given, Cost of TV with 10% GST = ₹ 8,800

$\Rightarrow$  $\frac{110}{100}$C =  8800

$\Rightarrow$  C = 8000

$\therefore$The original cost of the TV = ₹ 8,000

Explanation

Let the initial no. of pistachios ben.

At the end of first day, remaining no.=60%×n=0.6n

At the end of second day, remaining no=60%×0.6n=0.36n

0.36n=27⟹n=75

Hence, 75 pistachios were in the jar at the start of the first day.

Explanation

Step -1: Finding the work done by A and B in a day.

                 Let B takes a total of x days to complete the work alone.

                 So as know that A takes 6 days less than B we can write that A takes

                  x - 6 days to complete the work alone.

                 Work done by B in a day = x1​

                 Work done by A in a day = x−61​

Step -2: Finding x .

                 As we know that A and B together complete the work in 4 days,we can write

                 x1​+x−61​=41​

                 Taking LCM and solving we get,

                 x(x−6)x−6+x​=41​

                 x(x−6)2x−6​=41​

                 Cross - multiplying we get,

                 8x−24=x2−6x

                 x2−14x+24=0

                 x2−12x−2x+24=0

                 x(x−12)−2(x−12)=0

                 x=2,12

                 We will reject x=2 as x - 6 will become negative.

Hence, B takes 12 days to complete the work alone.
