Answer 1

Answer:

Step-by-step explanation:

Answer 2

(1) The number of bands Sunita had at the beginning is (a) 13.

(2) The number of points by which Mary was wrong is (a) 252.

Given:

(1) Josh has eleven red rubber bands. He gives Sunita three bands. Sunita now has twice the number of bands Josh has left.

(2) Instead of writing 860, Mary wrote 608.

To Find:

(1) The number of bands Sunita had at the beginning.

(2) The number of points by which Mary was wrong.

Solution:

(1) Let the number of bands Sunita had at the beginning be 'x'.

   Number of bands left with Josh = 11 - 3 = 8

   Number of bands Sunita has = x + 3

According to the problem, the equation becomes,

  ( x + 3 ) = 2 × 8

⇒ x = 16 - 3

⇒ x = 13

Hence, the number of bands Sunita had at the beginning is (a) 13.

(2) Correct point to be written by Mary = 860

    Incorrect point was written by Mary = 608

∴  Mary was wrong by = 860 - 608 points

                                            = 252 points

Hence, the number of points by which Mary was wrong is (a) 252.

Compiling both the answers, we see;

(1) The number of bands Sunita had at the beginning is (a) 13.

(2) The number of points by which Mary was wrong is (a) 252.
