Ans:
(a) Indra collected the most seeds.
(b) Seeds collected by Vicky = 42 Seeds collected by Sunil = 38 Number of more seeds Sunil should collect to be equal to Vicky = 42 − 38 = 4
(c) Number of seeds with Radhika = 24 If Radhika gets 6 more seeds, the total number of seeds with her will be 24 + 6 = 30 If Radhika gets 6 more seeds, then she will have 30 seeds.
(d) 3 children have more than 40 seeds.
(e) Gauri has 47 seeds. So, if she collects 3 more seeds, then the total number of seeds with her will be 47 + 3 = 50.

Player 1  93  7 
Player 2  97  3 
Player 3  89  11 
Player 4  99  1 
Fill in the Blanks:
Ans:
Century = 100 runs Double century = 2×100 = 200 runs
Triple century = 3×100 = 300 runs
Total runs = 206
Number of runs required to make 300 = 300 − 206 = 94
So, 94 more runs are required to make a triple century.

Jumping Animals
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) Bunny’s tenth jump is on square number _________.
(b) Tarru’s tenth jump is on square number _________.
(c) Gabru’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 Bunny’s 10th jump. Number of steps Bunny covers in 10 jumps = 10×5 = 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 Tarru’s 10th jump. Number of steps Tarru covers in 10 jumps = 10 ×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 Gabru’s 10th jump. Number of steps Gabru covers in 10 jumps = 10 ×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.
