**Ques 1: Fill in the Blanks:**

**Ans: **

Century = 100 runs Double century = 2Ã—100 = 200 runs

Triple century = 3Ã—100 = 300 runs

Total runs = 206

Number of runs required to make 300 = 300 âˆ’ 206 = 94

So, 94 more runs are required to make a triple century.

__Jumping Animals __**Ques 1:**

**Gabru, Bunny and Tarru are jumping all the way. Gabru jumps on every 7th square, Bunny on every 5th square, Tarru on every 4th square. ****Gabru starts jumping from square number 90. ****Bunny starts jumping from square number 99. ****Tarru starts jumping from square number 106. ****(a) Bunnyâ€™s tenth jump is on square number _________. ****(b) Tarruâ€™s tenth jump is on square number _________. ****(c) Gabruâ€™s tenth jump will be on square number ________. ****(d) Gabru and Bunny both jump on squares 104 _________ and ________. ****Find out: ****(e) Tarru and Bunny jump on squares _______, _______, _______ and _______. ****(f) Is there any square where all three of them jump? _______ ****(g) Guess who will finish in the least jumps? ________ In how many jumps? ________****Ans: **

**(a) **Bunny is on square number 99. Bunny jumps on every 5th square. In a single jump, Bunny covers 5 steps. We have to count Bunnyâ€™s 10th jump. Number of steps Bunny covers in 10 jumps = 10Ã—5 = 50

Thus, Square number reached by Bunny = 99 + 50 = 149**(b)** Tarru is on square number 106. Tarru jumps on every 4th square. In a single jump, Tarru covers 4 steps. We have to count Tarruâ€™s 10th jump. Number of steps Tarru covers in 10 jumps = 10 Ã—4 = 40

Thus, Square number reached by Tarru = 106 + 40 = 146**(c)** Gabru is on square number 90. Gabru jumps on every 7th square. In a single jump, Gabru covers 7 steps. We have to count Gabruâ€™s 10th jump. Number of steps Gabru covers in 10 jumps = 10 Ã—7 = 70 Thus, Square number reached by Gabru = 90 + 70 = 160**(d) **Gabru and Bunny both jump on squares 104 to __114__ and ___109___**(e)** Tarru and Bunny jump on squares 114, 134, 154 and 174.**(f)** All three of them jump together on square 174.**(g)** Gabru will finish it in the least number of jumps, that is, 8.
