Question

Pľéâśê §ôļvè ťhíś......It's urgent .Only number 6,7,8​

Answer 1

Answer:

6) ​Let the number of students in the class be x

Therefore, the contribution of each student is Rs. x

According to question,

x × x=1156

x² = 1156

x=  √1156

​x=  √34²

 ⇒x=34

The strength of the class is 34 students.

7) Let No. of rows= x

    No. of columns= x

According to the question,

x × x = 2025

x² = 2025

x = √2025

x = √45 ²

x = 45

The no. of chairs in each row is 45.

8.  

LCM = 2 x 3 x 5 x 4 x 3

LCM = 360

therefore,

LCM(8, 9, 10, 15) = 360 .

Since 2, 5, and 4 are not in pairs multiply by 2, 5, and 4 to make it a perfect square.

The required number=360×2×5×4 = 14,400

The least square number divisible by 8, 9, 10, 15 = 14400
