Short Answer Type Questions
Question 1.
Find the value of 11 × 16 by using Nikhilam formula with base 10.
Solution:
Value of 11 × 16 by Nikhilam sutra on base 10 is-
Directions-
(i) Closest base is 10, so deviations are +1 and +6.
(ii) Multiplic ation of deviations = (+1) × (+6) = 6.
(iii) On the left(RBSESolutions.com)hand side, write 11 + 6 = 17 or 16 + 1 = 17.
(iv) Required solution is 176.
Question 2.
Multiply by Nikhilam Sutra- 14 × 13.
Solution:
Question 3.
Multiply 11 × 15 by vedic(RBSESolutions.com)mathematics method.
Solution:
Directions –
(i) Closest base = 10 so deviations are + 1 and + 5.
(ii) Multiplication of deviations =1 × 5 – 5.
(iii) On the left(RBSESolutions.com)hand side, wirte 11 + 5 = 16 or 15 + 1 = 16.
(iv) Required solution is 165.
Question 4.
Multiply 9 × 11
Solution:
Directions –
(i) Closest base = 10, so deviations are -1 and 1.
(ii) Multiplication of deviations = -1 × 1 = -1.
(iii) On the left hand side, write 9 + 1 = 10 or 11 – 1 = 10.
(iv) Negative(RBSESolutions.com)number can not be put on right side. So borrow one carry from left side and make it positive.
(v) On the left and side, write 10 – 1 = 9.
(vi) Required solution is 99.
Question 5.
Multiply 14 × 17
Solution:
Directions –
(i) Closest base = 10 so deviations are +4 and +7.
(ii) Multiplication of deviations = 7 × 4 = 28.
(iii) On the left hand side, write 14 + 7 = 21 or 17 + 4 = 21.
(iv) On left(RBSESolutions.com)side there are 2 digits, so we have to shift one digit from right side (because base 10 has only one zero, therefore only one digit will remain on right side).
(v) On left side we will write 21 + 2 = 23.
(v) Required solution is 238.
Question 6.
Do subtraction- 753 – 584
Solution:
Directions –
(i) 4 can not be subtracted from 3, so add param mitra digit of 4 which is 6 in 3 and write the sum = 9 below in answer.
(ii) Put Ekanyun mark on 5 which is purvena digit of 3. i.e. \(\underset { . }{ 5 } \).
(iii) \(\underset { \bullet }{ 5 } =4\), 8 can(RBSESolutions.com)not be subtracted from 4, so add param mitra digit of 8 which is 2 in 4 and write the sum = 6 below in answer.
(iv) Put Ekanyun mark on 7 which is purvena digit of \(\underset { \bullet }{ 5 } \) i.e., \(\underset { \bullet }{ 7 } \)
(v) \(\underset { \bullet }{ 7 } \) = 6 – 5 = 1
Question 7.
Do subtraction- 8321 – 7654
Solution:
Directions –
(i) 4 can not be subtracted from 1 so add, param mitra digit of 4 which is 6 in 1 and write the sum = 7 below in answer.
(ii) Put Ekanyun mark on 2 which is purvena digit of 1 i.e. \(\underset { \bullet }{ 2 } \)
(iii) \(\underset { \bullet }{ 2 } =1\),5 can not be subtracted from 1 so add param mitra digit of 5 which is 5 in 1 and write the sum = 6 below in answer.
(iv) Put Ekanyun mark on 3(RBSESolutions.com)which is purvena digit of 2 i.e., 3.
(v) \(\underset { \bullet }{ 3 } =2\), 6 can not be subtracted from 2 so add param mitra digit of 6 which is 4 in 2 and write the sum = 6 below in answer.
(vi) Put Ekanyun mark on 8 which is purvena digit of 3 i.e. \(\underset { \cdot }{ 8 } \).
(vii) \(\underset { \bullet }{ 8 } \) = 7, write 7 – 7 = 0.
Question 8.
Subtract- 700 – 432
Solution:
Directions –
(i) 2 can not be subtracted from 0, so add param mitra digit of 2 which is 8 in 0 and write the sum = 8 below in answer and put Ekadhik mark on purvena digit of 2 in below number.
(ii) \(\overset { . }{ 3 } =4\),4 can not be subtracted from 0, so add param mitra digit of 4 which is 6 in 0 and write the sum = 6 below in answer.
(iii) Put Ekadhik mark on 4 (RBSESolutions.com)which is purvena digit of \overset { \bullet }{ 3 }.
(iv) \(\overset { \bullet }{ 4 } =5\), subtract 5 from 7 and write (7 – 5) = 2.
