? = 6885.009 - 419.999 - 94.989
= 6885 - 420 - 95 ? 6370
Correct Answer: 35
Explanation:
? = 840.003 ÷ 23.999
Here one number is increased and other is decreased to their nearest whole number
= 840 ÷ 24 = 35
Correct Answer: 240
Explanation:
? = 16.003 x 27.998 - 209.010
? ? 16 x 28 - 210 = 448 - 210
? = 238 ? 240
Correct Answer: 300
Explanation:
125.009 + 69.999 + 104.989 = ?
Lets assume, each value is approximated to nearest whole number
? ? ? 125 + 70 + 105
? ? ? 300
Correct Answer: 385
Explanation:
? = 127/8 x 116/5 + 19/5 x 41/8
= 14732/40 + 779/40 = 15511/40 = 387.7 ? 385
Correct Answer: 425
Explanation:
? = 23/5 x 15/26 x 283.75
? 13/5 x 15/16 x 284 = 426 ? 425
Correct Answer: 775
Explanation:
36.98276421 x 21.00002
Using nearest value in whole number for 36.9827421 is 37 and 21.0002 is 21
? 37 x 21 = 777 ? 775
Correct Answer: 2520
Explanation:
? = 14.995 x 8.001 x 20.991
? 15 x 8 x 21 = 2520
Correct Answer: 3400
Explanation:
26.823 x 27.923 x 4.5001
