We know,                     Re. 1 = 100 p ∴ Rs. 12 and 50 p = 12 × 100 p + 50 p                             .....

Solution: 160 ÷ 8[5 – 2{2 × 4 – (3-2) ̅ (28 ÷ 7 + 3)} – 4] = 160 ÷ 8[5 – 2{2 × 4 – 1(28 ÷ 7 + 3)} – 4] = 160 ÷ 8[5 – 2{2 × 4 – 1(4 + 3)} – .....

Solution:    30 ÷ [4 + 8 ÷ {3 + 5 ÷ (3 + 4 ÷  (4-2)')}] = 30 ÷ [4 + 8 ÷ {3 + 5 ÷ (3 + 4 ÷ 2)}] = 30 ÷ [4 + 8 ÷ {3 + 5 ÷ (3 + 2)}] = 30 ÷ [4 + 8 .....

Solution: Now, 144= 2 × 2 × 2 × 2 × 3 × 3     252= 2 × 2 × 3 × 3 × 7     360= 2 × 2 × 2 × 3 × 3 × 5 So, common factors = 2 × 2 .....

Solution: The required least number is the LCM of given numbers. The LCM = 2 × 2 × 2 × 3 × 7 × 19= 3192 Thus, the least number which is divisible by 112, 168 and 266 is .....

Solution: Here, start at + 15 and move 12 steps in the positive direction of the number line that is to the right and hence reaching 28.  (Number line figure in copy)   (+ 15) + (+ 13)  = + 28 or .....

Solution: Here, with one jump (+ 5), we move 5 steps in the positive direction, that is, to the right. So taking such two jumps (– 2), we move back by 10 steps.  (Number line figure in copy)    (+ 5) × (– 2) = .....

Solution: Here, start at – 6 and move 7 steps in the positive direction of the number line that is to the right and hence reaching 1. (Number line figure in copy)    (– 6) + (+ 7) = + 1 or .....
