Solution : Given: 35 ÷ 4 × 48 + 70 – 10 = 40
Interchange the digits and signs according to the options, to make the equation correct. Let's check each option – First option: 35 and 48, – and ÷ 48 – 4 × 35 + 70 ÷ 10 = 40 L.H.S.→48 – 4 × 35 + 7 48 – 140 + 7 = – 92 – 92 ≠ 40 Second option: 70 and 10, + and – 35 ÷ 4 × 48 – 10 + 70 = 40 L.H.S.→8.75 × 48 – 10 + 70 420 – 10 + 70 = 480 480 ≠ 40 Third option: 4 and 48, × and + 35 ÷ 48 + 4 × 70 – 10 = 40 L.H.S.→0.729 + 4 × 70 – 10 0.729 + 280 – 10 = 270.729 270.729 ≠ 40 Fourth option: 70 and 48, ÷ and × 35 × 4 ÷ 70 + 48 – 10 = 40 L.H.S.→2 + 48 – 10 = 40 40 = 40
So, only the fourth option satisfies the equation. Hence, the fourth option is correct.
