ANSWER KEY:
Q1. (1) + (1 × 9), + (3 × 9), + (5 × 9), + (7 × 9)
Q2. (5) + 416, + 208, + 104, + 52, + 26
Q3. (3) + 39, – 23, + 39, – 23, + 39
Q4. (3) Area of rectangle/आयत का क्षेत्रफल = length/लम्बाई × Breadth/चौड़ाई
= 35 × (35 – 14) = 35 ×21 = 735 sq. cm. /वर्ग सेमी.
Area of square/वर्ग का क्षेत्रफल = 
= 105 – 24 = 81 sq. cm. /वर्ग सेमी.
= 105 – 24 = 81 sq. cm. /वर्ग सेमी.
Side of square/वर्ग की भुजा = 
= 9 cm. /सेमी.
= 9 cm. /सेमी.
Perimeter of square/वर्ग का परिमाप = 4 × side/भुजा = 4 × 9 = 36 cm. /सेमी.

Q6. (3) Let the present age of Radha and Meena is 5x years and 7x years respectively.
माना राधा और मीना की वर्तमान आयु क्रमशः 5x वर्ष and 7x वर्ष हैं ।
5x + 8 = 28
5x = 28 - 8 = 20
x = 4
Age of Meena 6 years before/6 वर्ष पहले मीना की आयु = 7x – 6 = 7× 4 – 6 = 22 years/वर्ष
