4. Ruchi deposited 4370 in her account on Monday and then withdrew * 2875 on

Answer 1

Answer 3 :

Rohit's score in five succesive rounds are given as:

15 , -3 , -7 , 12 , 8

His total score at the end will be

= 15 + (-3) + (-7) + 12 + 8

= 15 -3 -7 +12 + 8

= 15 + 12 + 8 - 10

= 35 - 10

= 25.

Hence, Rohit total score at end will be 25.

Answer 4 :

Money deposited by Ruchi on Monday

= 4370

Money withdrawl on Tuesday

= 2875

money again deposited on next day

= 1550

Her total balance on Thursday

= 4370 - 2875 + 1550

= 5920 - 2875

= 3045 .

Hence, Her balance on

Thursday will be 3045.
