Question

2. The price of a TV is Rs 13,000. The sales tax charged on it is at the rate of 12%. Find the amount

that Vinod will have to pay if he buys it.

3. Find the cube root of each of the following number by prime factorisation method :

i) 91125 ii) 64

4. Solve :

5. Find the least number which must be subtracted from given numbers so as to get a perfect

square : 3250

Also find the square root of the perfect square so obtained.​

Answer 1

Answer:

2. He will have to pay 13000+1560=14560 (because 12% of 13000 is 1560)

3. (1.) Cube Root is 45

(2.) Cube Root is 4

4. the no. that should. be subtracted from 3250 so as to get a perfect square is 1

3250 - x = a²

3250 - x = 57²

x = 3250-3249 = 1

so , x = 1

because , if we subtract 1 from 3250 we get 3249 .

3250-1 = 3249

therefore,

√3249 = 57

hence , the square root of that no. will be 57 .

hope it helps !!
